Half-Cover that fits?

Has anyone had any luck i finding a half-cover that fits and doesn't fly off with the slightest breeze? I've tried two, and am evidently looking for Goldilocks.

I tried the Dowco Guardian (Sport Bike size), which indicates that it is sized to fit a 'busa, so figured it should fit the BB. It barely fits onto the bike, possibly extending 3in past the tail tip, and stays intact for anywhere from 30 seconds to 2 hours. (Returned for refund)

I tried the Nelson-rigg UV-2000, XL Size, as it is stated to fit a touring bike, and I'm riding with OEM bags. This cover fit just about like my full cover, but it was going to contact the hot muffler tips, defeating the purpose of a half cover. It was a giant sail if I didn't tuck it around the bags, so it was clearly not going to work. (Returned)

For me, this means ordering what looks as though it'll fit, once it comes in, jump on the interstate for a 90 minute round-trip to the bike shop (or pay $8 for shipping that I don't get back if I return the item), try it on, return if it doesn't work out. 3 trips so far, both I and Cycle Gear are at the losing end, UPS is making out just fine.

I don't really care if the side bags are covered I'm primarily wanting to give the dash a little protection from dust, UV, misting rain, and the same for the saddle. Depending upon which way the wind is blowing, I can get some nasty fallout on the bike while parked at work, so the cover helps out the paint on those 12-hour work days.

Cheers
