Ok, I sit too much on long trail rides, and wanted a more comfy seat. I saw a seat modded by these folks a while back in a post and decided to give them a try. They recommend widening the seat, so I asked for 7-8 inches at the widest point to avoid an eyesore, stock height, medium foam. They explain it will be about 1/2 inch taller than stock until you sit on it, which I think is accurate. I've had several rides on it now...it's very, very good. Nice workmanship, very comfy, fair price ($179, you send your seat), good communication.
