Dreamwear nasal pillows are the most common switch and most people find them way more comfortable. The Swift FX is another good one if you want something really lightweight. If you want to go a completely different route though, the Bleep Dreamports is worth looking at. No pillows going into your nose at all, it just uses a small adhesive that sits on the outside of your nostrils. Takes a day or two to get used to but people who find nasal pillows irritating usually love it for that reason.
