Is the ice cobra a factory two ply version? I believe the version camso sells is single play. I have that track on a BRP sled and it was falling apart at 3,500 miles. I think I sidewinder setup like yours would destroy it even quicker.
You already own all the parts so it may be worth trying, but I don’t think it will hold up as well as your backcountry.
Traction with the ice cobra was very good in soft and loose snow. Not great on frozen hard pack.
