glad to hear you like it. ive had an SVX1 for two years now and i absolutely love it.
i am not sure what the "spray skirt" that you mentioned, but the thigh straps are pretty cool. i havent got them for my Sevy, but a buddy of mine also happens to own an SVX [the two man version] and he has them and likes them a bunch. i bet with some practice you could roll that thing pretty easy. i dont like them because if i flip in our small technical rivers here in CO i want to be seperated from my craft and not get caught in the straps but thats just my opinion.
as far as carrying it, i got an NRS Sherpa kayak backpack
for mine that works great. it looks goofy at first because the SVX has that hard plastic keel running down the hull, but that is easily fixed. i took a piece of semi-tough foam [it was for rooftop cargo bars] and cut a long line down one side of it, about 1/3 of the way through the foam. i then wedge this onto the plastic keel, and it creates a flat, soft way of keeping the boat in place against the flat of the backpack.
dont let people getcha down either, the SVX kicks ass. people will rag on you because A) its a ducky, and B) its not a $2,000 AIRE ducky. Well, duckies are a blast, and for those of us that cant spend two g's on a boat, this works wonders!
