I bought the 97 nike irons.
Minimal difference between them and the rsi2 ones.
same distance to the millimeter.
left right deviation is maybe 1.5 feet on a 200 meter shot.
1.5 feet comes in handy, so for me worth the upgrade.
not a game changer at all.
p.s the 96 versa , is bought and booted again, I prefer the 94 nike putter.
