After just a quick glance, the only item I'd probably investigate further would be the COF-Wet....I've always heard 0.60 is the minimum you want...perhaps some of the pros on the board can chime in whether there will be a real world difference between 0.55 and 0.6. Go buy a few, wet them down and see how slippery they are. Otherwise, I don't like that they are not through body as any chips that you may get will show but for that price, it's probably not a deal breaker.
