i fished the pan wading several days a few weeks ago. did pretty well, but it was crowed even during the week and the flow was up over 300cfs but clear. i did really well on the upper pan above ruedi. the flows on the pan are now down under 200 cfs and green drakes are hatching - so it will be a busy place.
i also fished the roaring fork and colorado (drift trip) and we did very well. used a huge foam hopper (tan/yellow) with two droppers, one a tung prince nymph and the other a rusty spinner. lots of trout over 18".
good luck.
