I have one of Wil's seats on my Vision, could not be happier, the info you gives him will help him make your seat. I live in Washington state and shipped my seat to him, I have never met him, nor did I send him an imprint of my ass. I can tell you, he does some fantastic work. I also had one on a Vegas I owned for awhile and loved it too. I learned the hard way that the best seat you can buy is one built for you.
It is extremely likely that Will @ Cyclops can make you very happy. You don't need to mold the seat to literally match your assprint. I'd say that is likely to change over the course of a few years for many of us, yeah? The seat just needs to have the basic shape right. Shaped so that the foam can easily mold itself to you with even pressure (for lack of better term), and a space to stow your tailbone.
I had to replace the beautiful OEM seats on my bike almost immediately. For my bike and me- the Sargent was the way to go- and it has been the best money I ever spent on a bike. That OEM seat looked like a million bucks- but felt like a Flintstones relic. Hell my OEM unmodified Judge seat was WAY better than the slab that came on this thing. (Sargent does not have much for Vics, sorry to say)
Side note- Because I'm not here all the time anymore- if you start reading old crap about Will's troubles from years ago- ALL indications are that he is way WAY past all that. I feel very good about recommending that you disregard. Marriage is grand. Divorce is a hundred grand.
Just went for an hour ride on the new seat. I wouldn’t call it perfect but much better especially having a back rest. I thought it would set me back and down some but I’m up probably an inch and a little forward. Not sore like I was with the other seat so I’m happy with it.
