For feel, the Eye 2 with ZZ Lite top my list. So solid feeling. For all out forgiveness and straight shooting, stupid EZ to hit, I gotta go with the G10 in graphite, although the G15 and G20 compare. The G25, G30, G, G400 style clubs are all narrower sole, hotter face, stronger lofted sets and I do not prefer them over the G10. For pure beauty, the i200 might be the prettiest iron ever to my eye. I owned i5, i10 and i15 but lacked the striking consistency to get the most out of them. My favorite titanium faced irons are the Rapture V2, mostly because of the cool green and black graphite shafts. Hated the 2014 Karsten irons, not sure why. Hated the isi and ZING for feel and performance, except both those model wedges are very EZ to use. I'm sure I'll think of more.....
I play golf 3 to 5 times per week now, so I think I am done with steel shafts. Current gamers are G10 with TFC graphite.
