I have had the Mustang Saddle in rework for some time now. I am happy with the progress that has been made thus far. As you might know, I could not tolerate the original SERG saddle. It's a personal thing, but... it was a lower back issue for me.
I bought and received the Mustang Tour seat pictured earlier in this thread. It was comfy but positioned me too high and too far forward. I elected to modify this seat and have it disassembled in order to work the foam lower and further back. It has taken some time, but the results from Al's Custom Uplostry in Amarillo Texas, are very nice.
My cover of choice (although $) is black elephant.
Attached is the results of the modified Mustang Tour seat with the new cover, front half. The elephant hide is thicker than most upholstery folks are accustomed to... or, want to mess with, the labor is much more intensive.
Although the pic does not do this saddle justice, as it is incomplete; it will give you some idea of what I've been after...
I'm thinking this should look good on the Silver SERG ..
