Pricepoint has the Truvativ Stylo 3.3 on sale for $115 new...it is about 9 grams lighter than the XT crank...so lets call it equal weight wise....is it worth me spending an additional $85 to get the XT's new...or perhaps an additional 40 to get them slightly used off ebay ($155)? Anyone have an opinion on these two cranks? I want to keep my cost in check, but don't want to get junk. The stylo seems to get good reviews. Thanks!
