I had a set of TA-5 irons I got from Rock Bottom Golf for like 250 bucks. They had the TT sensicore shafts. I ended up putting UST-Mamiya shafts in the and played them for years. They were fine clubs.
I have the RTX wedges 50-54-58 and like them a lot.
Lately they just don't seem to garner much attention these days.
Srixon is the premium brand in that stable I believe and it seems they are slowly gaining traction as a brand besides in balls.
