I had some bugs with my St Axis, but once that got worked out I love them. Love the concept too. They are a little pricy though. Some friends of mine use Gold Tip and swear by them. I have taken notice and have looked at them carefully. I think they are a really good value, and what I'd recommend for the money. Acc's are awesome shafts, but are costly. My advice is to spend as much as you have to to get the results you need.
