Good luck in your search. Custom sounds the way to go. I have a modified stock seat and a Corbin. Neither one meets my needs.
Whatever happened to DJ? How's his Russell Day Long seat holding up?
To the OP, I have a Corbin too, I like it better than stock but I wouldn't ride it even half that far. It's comfortable for short rides, but not soft enough for the long haul.
I also have a stock seat recovered by Kontour, it isn't much more comfortable. It does however allow air to pass through it, and it's as cool at the end of any ride as when you first sit on it.
It's great for hot weather, but as you'de expect, brutal in the cold.
I also used to have a gel seat. I hated it. It was hard, hot, and never broke in. I find the New Image seat comfortable for about 15 minutes too, then I'm cramped and uncomfortable.
The above mentioned Day Long seat seems to be the way to go for comfort.
DJ has one on a B-King, but I don't know if anyone has one for the Busa yet.
