Mine is a Brooks Flyer which has done 4 years and 16,000 miles I guess. I was getting pimples also and suffered by the end of most all day rides. The pressure points were uncomfortable anyway lots. Then in China I found a MEMORY foam cover and haven't suffered since. It does accelerate holes in my golf shorts. Before that they went brown from rubbing the sweaty leather anyway. It did wash off although. Actually, the first 3000 miles on tour I had a rain cover on the seat permanent, it helped some.

I have found those other rubber blob pads are horrible sweat/ heat generators, was tried in my car.
