To me, Fins is pretty much the classic Moab trail, and you'll do just fine with your rig. Granted, it really is on the easier side of things, but I always have a great time on it. Dont be afraid to try the harder lines on it. Personally, the second half gets a bit on the tedious side though, so when we run it, its usually just the first half. It has some pretty decent drop downs and there's an optional waterfall that looks a lot more intimidating than it is (you can do it easy if its dry).
Poison Spider is also a pretty fun, yet on the easy side as well. I had a lot more fun doing this trail in the night though.
I guess it just depends on why you want to go down there. When I go down there, I mostly just like to relax and take it easy. Do a few simple trails, but mostly just take a nice easy going approach and treat it like I'm on vacation.
