Nice job. I'm thinking of tackling mine. Don't like it at all. I'm not so worried about sliding over, but I'd like to add some to the rear of the seat. I find the front edge of the seat cuts into my legs on long trips. Also, I like to sit up straight and it isn't comfortable with the amount of rear slope on these puppies.
