I got an untipped shaft to compare. Surprisingly, the tipped shaft feels much better and the numbers back that up. Dispersion better. Spin rate and apex height is higher too (shrug). Spin rate 4575 tipped vs. 4175 untipped. Apex height 96.3 tipped, 85.7 untipped. Head is a Stealth 2 Plus 19.5. Clearly club fitting is not all science. The good news is that I'd probably have a harder time selling a tipped shaft on eBay.
