Ok, I am thinking ahead for something to start saving for. I have a gap in my rod collection, i jump from 3wt to 7wt. I am looking for a place to start. I've cast a few but I haven't found a rod I like yet. Money isn't a concern, I'll make my final choice after casting them.

Just tell me what your favorite fishing rod in 4-5-6 weight is and why? What do you use it for (species, techniques and conditions)? What would you change (looks, parts, cork)? If you could have any rod what would it be? I'm looking for actual experience with the rod and not just a wish list.
