Tough to beat those prices since they come with two replacement blades. I have a pro stock L-2 + L-2 blade....it's a little bit blade heavy. Slightly noticeable compared to my other one piece sticks (Synergy SL, Bauer XXX). But once I'm actually playing, you don't really notice much. Unfortunately no grip on the L-2.
My roommate has an intermediate Synthesis (the previous version of the Synergy II). Paired with the carbon blade, it felt perfectly balanced. The blade didn't last too long, but he was using it outdoors.
Heard plenty of good things about the Warrior Dolomite tapered shaft. If you got noodle arms like me, you might appreciate the option of having a 75 flex senior shaft.
I always recomend the ultralite shaft. It uses standard blades, is very lightweight and durable. Very good shaft and not too pricey. The synergy II is basically a Synergy SL, the (matching) blades are expensive and not soo durable. I like tapered shafts myself but it's tough finding the right patterns. I have a couple cut OPSs that are cut for tapered blades that I'm selling for cheap if you're interested.
I went into a local sports shop today and asked what the difference was between tapered and non-tapered and I was told that tapered sticks allow for a more accurate and quick release.
Does it really make a huge noticable difference if it is tapered or not? I have a 100 dollar budget for the shaft.
For most people, no. And for using it on sportcourt you could use either but since there are better(more) options for standard shafts I'd go with what's more available. This year a few more blades than just the vector v40 will be standard short hosel blades so standard shafts will be offering you lower kickpoint options.
