I use incontinencechoice too, and have kylies with wings, that stay put; they're only about 5mm thick, I think it was the age concern ones I got.
I've also found they're great at making sure any pads you buy actually fit well.
Luckily I live near to the shop, but they've been good with samples, and let me bring back an unopened packet of pads when a sample fit better.
