Loren,
I am VERY interested in one of these seats! I am also 5'9" with 31" inseam, 175 pounds and the shape of the saddle that you're working on appears to be just right for me. I have tried the stock seat ,ZX14 seat and the Sargent seat. The height isn't the problem with any of them, but the shape. The workmanship of the Sargent leaves a bit to be desired in my opinion, the seams appear to be single stitched, a few of them appear to be a bit overstressed and the foam is not smoothly shaped, giving the seat an overall very "lumpy" appearance which I can't get used to.
I will buy one of these seats the minute that they are available. Would it be possible to get a stitching pattern similar to Russel's, I like the upholstery pattern of their seats but the shape is a bit much.
