My experience with CC was mixed, and agree, their prices are nutz!
Putter fitting: great results, shave a few strokes by shanging putters. Shorter, and from blade to mallet w/ toe hang.
Driver: OK, ended up in a shaft that I have fit myself to several times over the years, I've moved on from the head (425 LST ) to other LS heads and shaft still is "the One". Could have build myself for $100 less
Irons : Not sure they're working out, and build was not to the specs ordered, had to return to fix and was refunded 10% of my purchase cost With military discount and additional refund, about the same as buy from OEM, probbably about the same QC on spec.
I will say my local CC fitter has comp'd me some trackman time, so that's been nice to dial in some numbers.
My iron fittings were bad at CC. On two different occasions. Never was fit for a driver, they told me both times the driver I had was just as good as anything they could put me in, I did like that (I felt they were being honest and not just trying to put me into some pricey driver). Putter fitting was excellent as well, I was put in a Edel that had less loft (I dont forward press) and a basic alignment marking, it's been massive in my lag putting and being more aggressive at the hole.
