Thanks niblick.
Here are excerpts...
..."Dr. Aaron Zick...explained why any club that has perimeter weighting is harder to clubface manipulate than one with evenly distributed weight. Now we know why Tiger, Johnny, Jack, Arnie, Sam, Ben, Byron, and Bobby, all used this type of iron.
....As an engineer (BS in Aeronautics) I have been trying to tell people this since I started playing golf. It just made sense to me given my knoweldge of physics and dynamics. While MOI does resist twisting on off-center hits, it also makes clubface control MORE difficult. Not less! Now I can say that even a respected PhD in the golf industry agrees. Ever think that maybe some of those off-center hits you need forgiveness for are because you are having a hard time controlling the clubface??? Blades are not the devil. They are the instruments of real golf swings.
...regarding the cb or muscleback designs: the mb would be the one for clubface control, which to me would be to work the ball more. but if not hitting the sweetspot, wouldn't the cb still be more preferred?
My questions:
Regarding today's golf balls, they basically go straighter today. Does this make blades even more important (or less) for shot shaping?
Still wondering the differences when one switches from cavity to blades or vice versa and what impact it had on your game...
Are blades that much less forgiving?
Is feel, the feedback from blades different than some of the newer forged cavity backs?
