Should have bought it from N.America where I check all the spearshafts for straitness!

Kidding and in light of your situation probably not funny to you...
I just realized how old this thread is but just in case and FYI the Cayman is 7 years better than the Excal. The Excal is a great gun for the $ but there is no comparison on a technical level.
The gun I think would work really well for swampfoxgolf is the Cayman Cave.
Cayman handle/18mm power bands/4 prong/55cm - fresh water killer and most likely plenty enough for your uncle's house in the Florida Gulf.
