Boy, you hardly let a fella get a word in edgewise!
I like components. They're cheaper than OEMs, perform just as well, and are just begging to be custom fit.
SMT (superior metal technology) has customer service and a lifetime warranty that is second to none.
Tom Wishon Golf Technology is a list of Wishon builders.
I'm pretty sure GolfSmith has a European distributorship - they make some decent stuff (I played their Snake Eyes 600XC
irons last year).
The SMT Spectrum was the first component driver I ever had - shafted it up with an AccuFLEX Evolution.
My bag is currently owned by Wishon stuff - a 949mc driver, 515 and 949 fairway woods, the 560
irons (forged, low offset cavity back
irons), and their CX Micro wedges.
You're headed down the right path (custom fitting), but are already flirting with the darkside... (clubmaking).
