Wood is the only way to go. Composite blades have little "feel" to them, and make it very difficult to catch a pass, shoot, pass, stickhandle, etc. But they look good, I guess, to some people!
I currently use Sher-Wood PMP 5030's, because they last about 15 games or so, and cost $22 American (if you know where to shop!). Compared to a one-piece stick at $190 that will break inside of one season. I play 4 times a week, so a one-piece wouldn't be very worthwhile. I can buy 8 wood sticks for the same price, but 8 wood sticks will last me almost 2 seasons, PLUS they are better for playing defense (blocking shots, whacking at the puck, etc.). I also have a 2-piece aluminum/graphite shaft, but don't really like it much. It's WAAAYYY too much bother having to change blades that often, because they break quicker than a wood stick does, and blades cost the same ($21), plus you have to buy and carry a heat gun in your bag, etc.
I also have a new Christian Bros. wood stick that feels AWESOME. I will use it in a game for the first time next week. But I grew up with Christian sticks, and love them.
