I played with an inexpensive set the first year I played, then went and got fitted. Callaway was the brand that worked with my swing, and I've used them ever since. I am considering getting fitted again -- I'd like to see if the Adams iron/hybrids would work for me.
i've always been a Callaway fan. I've met a lot of people who don't like them, but i have yet to hit a set that didn't feel good, all the way back to the S2H2s. now granted, some of their sets over the years have had huge club heads that i don't think i could play, but they at least felt good.
with saying that, i've heard a lot of good things about the Adams iron/hybrid set. talked to a couple people who have them and love them. considering a lot of people are replacing their 3 and 4 (and sometimes 5) irons with hybrids, it makes sense to tailor a set around that concept.
