(10) Cast a bubble. Small spinning bubbles and trout flies are an often overlooked combination. Rig a Hare's Ear Nymph 3 feet below a small casting bubble, or-if the trout are rising-use a small dry fly. You'll be able to cast this rig quite far and then be able to drift it without drag in the slow currents of a big pool. Your ultralight line is more than fine enough as a leader, being equivalent to the 6X or 7X tippets that flyfishermen like to brag about using. Ultralight-spinning guys, of course, fish that fine all the time.
