I have:

Cobra King F7 2-3 & 3-4 Hybrid, Stiff Flex Fujikura Shafts
Cobra King F7 5-PW Irons, Regular Flex Steel Shafts
Standard Lie

About a season's worth of play on them, in good shape, grips are good.

Looking to trade for a set of similar quality but with a stiff shaft. Simply put, I got some lessons after I was "fitted" for these at GT, and my swing speed and lag improved and now the shafts are a little soft for me. Perfect for anyone who needs a regular flex. Paid $1000 brand new halfway through last season.
