Like the other guys said, it’s a legal club so the cor is not outside legal numbers. The thread I started before about Krank making drivers based off of swing speed is what you are thinking. The Krank drivers like that are illegal in USGA events.
The thing with ALL legal drivers is there is a ball speed where if you are below that number you do not get the same benefit/ trampoline effect for distance as some one at or above the number.
The Rhapsody is just a lighter head that is very forgiving. I’ve been telling you for a few years to give it up and just hit that head... it’s the one you ALWAYS hit the best. Buy a few shaft adapters for it if you want to screw around with shafts, but keep using that head.
The new G le2 head And maybe the g812 junior head...
