I rent a small pontoon, I like it. The UL spin and a 3wt fly rod is what I use for all trout, although the biggest I have caught is 24". I guess I tend to catch lots of smaller trout, same at Taneycomo. But 4-5# trout is fine on that light gear and a lot of fun. I use barbless hooks, I don't care if I lose a few. The San Juan river is a slouch I guess compared to Taneycomo. I do have a friend that caught a 30# brown on Cebolla creek in the Jemez of all places, so it does happen, just never to me .. yet. I am going to up size baits in the future at Taneycomo.
Good luck, great place.
