Yeah, I think it just boils down to personal preference. I had a Sunshine pony (also a Beach Ball) with a stripe that was so frizzed that I wouldn't even call it 'hair' anymore. It was basically a plastic brillo pad, lol. My solution was to purge all Sunshine ponies from my collection. But if I'd wanted to keep them, I would have tried the low heat method and replaced the stripes if it hadn't worked. I don't mind the occasional haircut but I can't stand frizz.
