1. If Iron Byron is set-up to hit a straight ball, what one thing you could change, would cause the ball to slice? Open face
2. If the clubface stays "square to the path" where does the face need to be at impact for a straight shot? Slightly open
3. Where on the golf ball would the club contact for a straight ball? Inside aft quadrant
4. If the clubface squares up at or before low point, which direction is the clubhead moving in at impact? Down and out
5. When does the lie angle of the club have to be "flat to the ground" for the ball to fly straight? Separation
6. If the golf club swings through the ball on the plane angle of the lie of the club, how long does the club swing "down the line"? Only one moment, at low point
7. If the path (or plane line if you wish) is 4° to the right and the face of the club is 2° closed (pointing to the left), which direction does the ball start in? Left
8. All things being equal, shallowing the swing plane through impact will produce what result? Lower ballflight
9. In the most efficient swing possible, would the hips continue to move at a continuous or increasing speed through impact? Given only those two options, continuous (otherwise, slowing)
10. Why do shafts bend more forward on offset golf clubs? Center of gravity farther back

1. Open clubface
2. slightly open
3. inside aft quadrant
4. face and head are independent...can't tell. head could be going out to in for a pull, or in to out for a pull draw. Everyone else is saying down out and forward...maybe this is where all are gonig wrong
5. Separation
6. I microsecond...no straight lines on a circle
7. about straight...TGM says a little left, but path has some effect
8. less spin, more boring flight
9. continuous
10. clubhead COG wants to align with shaft, in offset clubs it is further from shaft line at start, so it moves further in an attempt to align.[/QUOTE]

1. open the clubface
2. slightly open
3. inside aft quadrant
4. same direction as before, clubface alignment doesn't control clubhead path travel
5. low point
6. at one point only
7. Assuming the path/plane is 4* open to the target line and the face is 2* closed to the path, the ball should start off at 2 plus* of the target line and move towards the target line as it travels (draw)
8. lower trajectory and possible draw???
9. increasing
10. cog location
2. slightly open

Trick Question:
9. In the most efficient swing possible, would the hips continue to move at a continuous or increasing speed through impact?

Answer: No.
....
Answer is Yes.....
Although in the most efficient swing possible there would be no hip movement at all so there would be no continuation of anything)....
The most efficient "swing" is a pendulum motion where the max work needed is to raise the heaviest end of an object to its highest point before release, whereby it returns under the force of gravity. Therefore, Minimum work + gravity = maximum efficiency. No hip turn involved.....

If the choice is between constant speed vs. accelerated hip speed through impact...I'll pick constant.
May be matter of interpreting question...
I agree with you that the ball has departed clubface when sole hits the ground therfore makes little difference ...
but could he mean in a correctly aligned swing which is hitting the ball straight anyway... when will ( lie angle / sole) be flat to the ground...
or are we all misreading "lie angle" as "sole" and Brian means something else?
Well, if all the impact alighnments are for a straight shot, then the sole of the club needs to be parallel to the ground at seperation.... BUT a slight variation of open or closed can change the variation of toe up or toe down. Otherwise people could not hit a straight shot ever with the toe digging slightly into the ground. But with a slightly closed clubface and toe down, it can be balanced out. So maybe we could just say that the question is incomplete.

no because all the kinetic energy would have been transfered from the hips and the shoulders would be stopped as well

1. open clubface
2. slightly open
3. inside aft quadrant
4. down and out
5. when ball separates from club face
6. there is no straight down the line, only curve
7. left
8. lower trajectory, starting left and further drawing slightly left.
9. If efficiency is meant to refer to work done and clubhead speed obtained it can’t be either of the two options given. I previously picked ‘continuous’ being not optimum choice but the better of the two options allowed.
The optimum efficiency in energy transfer occurs with the hips decelerating before impact to allow them to give up their kinetic energy in time before impact to more distal parts. Optimum efficiency is obtained with the hips have given up all their kinetic energy, hence have come to a stop.
Through and past impact the hips might pick up again some motion due to the reverse flow of momentum/kinetic energy as the large momentum/kinetic energy of the clubhead is now flowing back into the golfer where it is dissipated.
10. larger centrifugal force

hips transmit or allow velocity correct? If that is the case then the speed of the hips would be increasing through impact to allow for max velocity through impact.
I feel like a nerd.

Question 9 kind of reads like a multiple choice question, rather than a yes or no. It has been said on this site numerous times that the hips slow or stop at or near impact, but the question dosen't sound like that is an option for an answer.
That said, my revised answers are:
1. Open the face.
2. slightly open to the target line
3. inside-aft quadrant
4. downward, outward, forward
5. separation
6. momentarily
7. the direction the clubface is facing
8. higher ball flight w/ less spin
9. no: If the hips don't slow or stop, they don't transfer their energy to the next components in the kinetic chain as efficiently
10. sweetspot is farther behind the shaft

I see,
After reading 7-15, I get the impression that the hips permit other actions, thus my above post. The hips have to clear or else roundhousing will occur. Most swings I looked at have a last second acceleration of the hips just before and through impact.

slowing down and stopped are two different things
slowing down shows they still have some energy

1. open the clubface
2. slightly open (a few degrees)
3. inside-aft quadrant
4. down/out
5. clubhead correct lie angle at SEPARATION
6. impact or low point
7. LEFT!! (garrrr!!!)
8. lower trajectory, less spin
9. depends on the person...is there A most efficient swing possible??
