The X:60 is still probably my favorite stick that i've ever used. Not necessarily the best, but still the stick that i was more comfortable with which is the most important thing at the end of the day.
I also play a ton of roller/ball hockey, both outdoor and indoor on all kinds of different surfaces. Obviously most outdoor surfaces are too rough for pure composite blades (as well as wood blades.) Literally just 5 minutes on most outdoor surfaces will ruin those types of blades. Most good outdoor blades come on wood/fiberglass shafts, so they're obviously heavier than a composite. Koho had a few good lines out, especially if you're using a ball. The Torpedo 2260 was fairly light and had a good blade, but they're tough to find now. But the ideal stick that i've found for roller hockey is the old Montreal Nitro 8500. Hockeyworld.com (Perani's) sells them, and luckily i have 3 of their shops within a reasonable distance from me. All of the old Montreal's are on closeout so i now own 7 of them that i got for $30-40 a stick. Whether you're playing indoors or outdoors, with a puck or a ball, it's great for roller hockey. Unfortunately they'll be completely extinct before too long, thus my stockpiling of them. To my knowledge, very few 1-pieces made today have a blade that can withstand outdoor surfaces.
I've also used the Easton Synergy ABS blade on good shafts (x:60 and Dolomite) for roller, but i still prefer the feel of the Montreal 1-piece.
