I run gatorskins on my fixed (2 punctures in the last 6 months but dug plenty of bits of glass out that haven't penetrated so I'm happy) and GP4000 on my geared bike (none so far but prob done half as many miles in the same time).
Happy with both so far, esp as I am a fat git who prob puts more strain on his rubber than most of you fatherweight boys/girls.
