First: Does anyone have a recommendation for what kind of rod and reel would be good for backpacking trips into the Sierras? I have a 5wt two piece, but I figure a lot of the fish will be smaller and it would be nice to have a 4 piece to break down even further.

Second: What do you do when you want to have the option of two different types of line on your reel? Lets say I plan on doing some dry fly fishing, but if that doesn't work I want to throw streamers so I want a sinking line. Do you have two separate reels that you carry with you?

Last: How do you even pick a reel? I will primarily be fishing for trout, but I would like the option to fish for steelhead and striper as well.
