The V-15 sticks out as the thickest blade in the line (7.0mm), and shares the same speed as the fast V-11. If you play a high-level game of tactical blocks with put-away loops, then you can't go wrong here.
The T-7 plays a bit between the Butterfly Maze and Iolite blades and is great for an attacking and looping game with increased feel and control over a pure carbon blend.
