The minoura quick release is much better than the cycle ops. The cycle ops is harder to lock into place and the ball on the quick release handle has fallen off on 2 of the ones I've used. I've only used the V150, and not the other red one. I was a little skeptical at first because it didn't look as sleek and modern as the cycleops or blackburn, but it worked really well and ran smoothly. I agree with the other post about the remote shifter. It just kind of gets in the way, and your bike shifters will change the resistance anyway.
