They will customize the seat while you wait, and have you sit on it to make sure it's what you want. He also offers alterations for a year so that you can get some seat time and really make sure it's comfortable.
Had my wifes seat on her Heritage modified with heat and relief cut for her tail bone. Also had a custom back rest done for her since she has a reduced reach seat. they took the time to take photos of her seating on her bike and took measurments while we were in Cripple Creek. then when we got home sent her seat in and was happy with the turn around time.
When I had my seat redone this winter, The gel pad went next to the seat pan , not on top, then different memory foam for my weight was installed on top, I`m thinking the gel was for vibration,and shock, not for butt comfort. Thats the job of the foam.
