It's best to have a rigid and inflatable combination for snow and ice.
If you rely on an inflatable pad and it punctures, then you're in trouble.
Many take a ridge-rest type closed-cell pad with inflatable pad on top.
I invested in a Therm-a-rest Toughskin and love it.
My older Pacific Outdoor Hyper Mtn pad is for saving weight.
Cheers!
