I had a stock rear Winzip disc brake on my Sun SX-x3 trike which wasn't worth it's weight in crap! I changed to the Avid BB7 MTN and it's a world of difference! The one thing I liked about the Winzip was the look of the rotor because the holes drilled all over it.

If I were to change back to the other rotor is it going to effect the way the Avid stops, or shorten the life of the pads from all of the holes?

Thanks,
Mr Gnome
