To get a new bum rest! After so much research and countless hours scouring the net and consultation, I decided on a ISM. Great reviews for the most part and while not for everyone, most seem to enjoy theirs after getting it set up properly as they do not set up like a traditional saddle. I opted for the PL-1.0 and will now do some rides to perform final adjustments. Will report back my likes and dislikes in the future.
