Can't say anything about the crosswater or redfly rods, but the RS3 rods are awesome... I've been on some kind of weird search for the best fly rod for me. I agree wtih Devil because I started out with the TICR 5wt and that seemed too heavy, stout, and unbalanced - it seemed too top heavy even after trying to balance the wt with the reel. And after a day of fishing with it, I was exhausted so I returned it for a 8'4 wt pro series and that was pretty decent, but then went back to the shop and tried a Redington RS3 and immediately fell in love with it! It was light and had the action that I've been looking for.

Once again, try it out first. Only you can decide what fits you and what doesn't as for me, I love my Redington and would probably choose it over TFO rods when it comes to 5wts or over. But great rods overall.
