Just a quick update. I've been playing with VS Team / Polyfibre Poly Hitec 18 for about 5 days (10 hours) and I'm loving it. It plays very similar, but is quite a bit more comfy than co focus 17L. I felt the comfort factor within the first few hits. Will post more when the tournament wraps up and I get back home.
