Recommendations from shop owners and others suggest that when buying (and using) multiple rods choose two weights different eg, a 4 wt and a 6 wt. I mostly fish from a boat or canoe and I carry rods 1 weight apart (5 & 6 wts) and it seems to work for me -- one with a streamer and the other with a dry. I like to hear from others that may do this same thing. Thanks Dave
