OK, I putted with it for a while, and I see what you mean. If it hits anything sharp, it slices into it like a knife through warm butter. This is very very very different from the first white protege Clutch I got earlier this year...so, not all white clutches are bad. Basically, look for the tacky chalky-feeling plastic, that's the best stuff.
The Clutch is generally a great disc, but my impression is still the same, that it lacks glide in comparison with other putters. Very stable, but it just drops faster than an Aviar or Wizard. This isn't necessarily a bad thing, just have to adjust your putts a bit and get a little more zing on the throw to keep it up.
