[12 piece bucket]

nice...

is one better geometry than the other? does one have more power/physics

Depends on the player/shot at hand/preferences/grip type/all that trackman stuff/......lots of variables to manipulate.....

Would be interesting to see how much shaft lean the greats produced with say a 5 iron....a few ways to lean it too...lean AND raise the handle up...Lean it and don't...with the hands with the body or both...Hogan and Nicklaus didn't produce huge amounts of lean...one had lots of #2 to let out and the other one didn't...Lee Buck opposite end of spectrum...better get the right amount of lean to get the face open enough not to start the ball left.







So you can see the other side of the angle of attack is the angle of ascent....another strong gripper like Lee Buck is Couples but his "arc" is gonna be "shorter"...quicker rate of ascent...faster "recocking" through the ball...thus hits a higher ball...
