Thanks Brian, I've seen Winslow's website, very nice inserts indeed. I do not have a lathe...someday!
I found the XP blank on the flebay, it's 9'6" 5wt. I can't wait to start putting it together. I sent some cork rings to Diver Dan to cut down for me and now that the seat and guides are on the way it shouldn't be long.
Maybe this is a silly question, it is the obvious question though: What are the reasons that one could/should not use an uplocking seat that has a standard shaped hood and just reverse it to make it lock down?
I am thinking about this type of seat (from ebay, looks good by the image and is pretty cheap)
