I found a custom upholstry shop that specializes in moto seats. The guy sounds like he knows what he's talking about and the price is reasonable so I think I'm going to try a custom job. Seems like custom is the only way to get everything I want. Thanks for all the feedback.
BTW, just got back yesterday from a "sage rat hunting" tournament in Eastern Oregon (believe it or not). Rode the V there on the backroads through some of the most beautiful country. Love that bike. Stock seat actually felt pretty good - but I'm normally an off road rider so anything wider than a 2 X 4 feels like a couch!
