One board to rule them all
When I got into SUP I was hoping to get one board that would be relatively good at most things. I am now of the opinion that no such thing exists. I have played with fiber, epoxy, plastic and inflatable boards and think each one has it's uses (almost). If you are going to be in OK for a while, get a hard board. If you want to do SUP as exercise, get a touring board but if you want it as an exploratory/fishing/noodling craft I'd get a wider, more all round shape. Inflatable boards are great for beginners and rivers but are mediocre for flatwater and surfing.
If you move back to CO and get into river SUP, just count on adding to your quiver.
