hi glenn, why not get it professionally re-shaped? i got my sportsbike seat done exactly how i wanted,(i showed them a page from the corbin catalogue!) and 2weeks later they had done a grand job.third of the price too, although it is done on your old baseplate. i should think a slabby trail seat with a 1 peice cover would be quite cheap. look in the back of a biking magazine, i went to "bumwraps" in bognor regis, i can get u their email address if u want,they even send u a load of samples of all the vinyls they do so you can hold them up against your bike, like a dulux sample card!
