yea they adjust or check for for smash factor, angle of attack, swing weight, lie, length,,. i have a high ball flight compared to my friends and i love it, they're jealous but they're also 2 clubs longer then me. doesnt bother me i would rather be accurate then spraying all over. plus it has to do with a 3/4 back swing which doesnt make me swing out of my shoes. arms get to fast, wrist too slow, club opens open and spray to right. this way more tempo to close down the wrists and control the ball............but thats just me............now the driver,grip it and rip it
