Another vote for the Wildwater Rod, I have the HX 4 pc. 9 ft. 5 wt. and the reel to match. Very nice product.

I also do some backpacking. Usually, it is on small brook trout streams. I carry an Elkhorn 4 pc. 2 wt., again with the matching reel.

I think that most 4 piece rods, 8 foot long or under, whatever the weight, are very packable.
I use the rod tube that came with the 2 weight and simply carry the reel in a zippered outside pocket. A small fly box with about two dozen flies, a spool of tippet, a pair of nippers, a pair of forceps and I'm ready to go.
