Alright, it's not a saddle, but I am currently really annoyed with my xop seat cushion. Mesh replacement seats are out there, but I got to wondering if a fellow could just jigsaw out all the guts from the existing seat to leave a hollow seat frame, then weave paracord for a softer seat. I don't have any experience with cast aluminum, so I'd like to get your take on things. I weight 210, it that helps.
