REI gear << cash or airline miles
Airline cards charge for their cards or have restrictions- no interest here. BTW, if you hang out and wait till like July, you can get cash on an REI card, instead of gear.
I pay no fees for my airline mileage award visa (I don't carry a balance on it) and the only restrictions are blackout dates for flights. Even so, I am skiing in the alps next winter and used miles to book the flight.
