it is a really nice shaft. much better than any other i can recall ever hitting. it took a good week to get used to, but now i'm long & accurate.
if you've got a good tempo, i'd really reccomend trying one out. as long as you know where your swing is going & what it's doing, then it shouldn't be a problem.
know what your ss is approx. the s flex is pretty stiff. i think you can still get these shafts in 580xd's from 3balls.com for pretty cheap. i paid 170 usd for mine, & that was a bargain.
