Having seen how well Stuart's Skookum faired in the jungle of Borneo in A2, I would go with that too. I think that a single bevel scandi in S30V would be just a little too hard to sharpen to be fun, while the A2 was lovely to sharpen. O-1 is nice, but A2 will resist the damp just a bit better.

You can spend time, and you can spend money. Sometimes you can end up spending both, but you will never get anywhere without committing to spending at least one or the other....Sometimes money is cheaper than time.
