You might want to check out the Ultralight Flyfishing Forum. These guys know everything there is to know about ultralight rods and are eager to share their knowledge.

There is a 2 wt shootout coming out shortly at the Flyfish Ohio web site.

I had a chance to fish a few of the rods (there were 23 total) last weekend with these guys at the FFO Conclave, all 2wts. My favorites of the bunch I got my hands on (strictly from a performance perspective) were the Echo Carbon, a Hardy (I can't remember the model) and a TFO Finesse.
