I've tried four different expensive saddles with cut-outs, but none were comfortable enough for long rides, plus they were all heavier than the comfotable regular saddle I have. So I was wondering, why not make a slit in the cover from the top and make an appropriate sized cut-out underneath, then pull the material from the top through the cut-out and glue it to the under side (and trim to make neat). Only question becomes then is what glue to use? Gorilla glue? Anybody see a downside to doing something like this?
