Hi Daniel,
would love to see another Mossie in the US, certainly it would be easier to handle than a Taipan for a guy your size and easier to right after a capsize, as long as you seal the mast (the mast section we use in OZ is very light and a metre shorter than a Taipan).
But that said, some Aussie Taipan sailors are quite succesful at 70ish KG not to sure of just how light, but not sure how they go righting them after capsize.
