I've never seen the brace beam on the top before but I think doing it that way will create to much load on them. I have the Mystere wings and an abrupt hit from an unbalanced body will break that weld where the small pipe attaches to the larger. Prindle sold a set of wings that went into a kit to reinforce the end cap area without the smaller pipe for the 18-2 and 19 maybe performance has them for the Nacra type tubing ....
