as previously stated, definitely not a 3 wt. I would start out trying a 7 or 8 wt. and go from there...it was probably designed to cast an 8 wt. but use whatever line feels the best on it...I have an old glass rod that is supposed to be a 6 wt. and it throws anything from a 4 to 8 well...I like it best with a 5.

ask this question on the "fiberglass flyrodders forum"...do a google search and you'll find it. There are a bunch of people there that can more than answer your question for you and then some.
