Erik, Jazz does put up a bit of a struggle, (squirming, mostly) but the minute the suit is on, he's fine and couldn't care less. He's been wearing flight suits since before he was completely weaned, so he's pretty used to it. He's also just fine with towels, and sometimes he'll even take a nap on his back while wrapped up.
That said, if I don't keep toweling him and putting the suit on regularly, he will get wild quickly.
That's mostly what Chicken does when I wrap him in a paper towel - squirming. Sometimes he likes to tear off a piece, chew on it for awhile, then let it drop on the floor. He's fine with a regular towel, though. Anyway, I'm considering letting his flight feathers grow out, so a flight suit might be in his future!
