I think people make Crane harder than what it really is. MY usual trip there is downstream from the park I hike about a mile down stream and work my way back to the far end of the park. I always wade, unless of course I see redds. I usually catch at least one fish in every riffle/hole. Cast up stream with an indicator and that is all there is too it. San Juan Worms are always my go to fly at crane, followed by buggers, and the occasional match the hatch, but the majority f the fish I catch at Crane are on nymphs. As far as tippet, they aren't pick, just match your flies. I usually use 6x for my nymphs, but I have caught plenty of fish on 5x, I only use 7x if I m throwing dries, which really isn't that often. I fish Crane every regularly and don't have problems catching fish, and I am not that great of a fly fisherman.
