How many miles are on those Aksiums? The price seems a little high to me.
On the plus side, they're what I have on my bike, and as far as sturdiness of spokes and rims, they've been rock solid. I might get them trued once a year but they've never really needed it.
On the minus side, my freehub bearings failed around 10,000 miles, and of course they're heavy as all get-out.
I guess to me it depends on how badly you want rid of your current bike. I think if you can live with the frame for a while, if it were me, I'd see if you could borrow a wheel from a friend for the Hilly (or even rent one from a LBS, even if you have to rent the whole rest of the bike along with it), and in the meantime have a really good wheelset built - wheels that will be an upgrade for you whenever you get your new bike - or that you can put on the new bike when you have it built.
