Hi Mark- Call me if you have any questions about them. I was tuaght by Sensei Joe Blados ( soon to be proud owner of a new 21 ft, Maverick with 225 HP Merc.). Plus I added the mylar fabric cover, which gioves a nice scaley effect. It's important to wrap the shank with some kind of heavy thread-I use old backing- and to soak it with accelerator, then put the THICK CA on the foam-and watch your fingers!! If you like we could do an exchange-crease flies for whatever you like.
