I just got back from a trip to Yellowstone. I built a rod tube with a flourescent lamp guard I picked up at Home Depot for $4 and some duct tape. Weighs almost nothing. More details here: http://www.backpackinglight.com/cgi...ums/thread_display.html?forum_thread_id=12206 Also, after quite a bit of research I went with the Thermarest Neoair sleeping pad. Reviews are all over the map but I had no problems and found it very comfortable. The regular size comes in at 14 oz. You do pay for that comfort but long term it was worth it to me. I'm not sure how you can carry a raft, paddles, waders, boots, etc. Not only weight but bulk. Try packing your backpack ahead of time and see how it's going to work out. I fished the Lamar River in warm weather wearing Tevas so didn't have to worry about all the extra wading and flotation gear. Good luck and have a great time!
