Bruce,
I guess my main concern is the carbon fiber mast on the 17R. I'm thinking it would be okay with the opposite shroud supporting the added trap weight............but I would feel a lot better knowing someone had already tested it.
I'm not sure if the 17R mast is the same mast as the I-20 only shorter. I have heard both that it was and that it wasn't. Never actually compared the two.
