quote: Again this is a blatant assumption and without a set of specifications of this "person" you're talking about can't just assume. Also an 8.5* driver should carry the ball less because there will be less spin than with the 11* driver and depending on the swing speed, shaft, ball speed, etc etc....the 11* may be too much loft creating too much spin and therefore ballooning shots for the person who hit the drive and actually carry LESS than the 8.5*.
People are having the impression of using a less loft driver will get them further, is that they thought the ball will fly better if the ball is flying low on a (Back wind) windy day. Again it is all depending on whether you are facing LOL High wind or low wind or even break wind.
If you are talking about the general average golfer, then yes. Most of them should be using high lofted drivers as they don't have enough swing/ball speed to use a lower lofted driver.
I presume using different loft driver will only affect the roll on the ground rather then the carry. I believe it will make a different if we are playing on a soft ground.
Not true, more loft = more backspin and less sidespin. Thats a fact. If you took me and fitted me for an 8.5* driver and a 11* driver i would probably carry the 11* driver about 10-15 yards further than the 8.5* but there would be very little roll due to the excess spin the 11* would provide.
Also one thing you failed to specify as well is driver head design. If i was using a Tour issued head i might go up 1-1.5* in loft to help counteract the lower launching/higher COG head. Or if i was using a big 460cc head versus something smaller. You usually have to go up 1* in the bigger heads because the COG is so far away from the face/ball the spin is much lower and you need to be able to get it in the air high enough.
So as i said before:
waaaaaaaaaaaaaay too many variables
