Deciding on a New 5 or 6 weight
While I am not the accomplished fly fisherman some of the other guys areI would still like to offer my opinion. Regarding the brand or model I suggest you let one of the people at LRO suit up several different outfits and try them without looking at brands to find the correct feel. I did that and purchased the z axis, I am happy with it.
As far as which weight if you fish with a lot of streamers I would go with the 6 weight otherwise I choose the 5 wieght for its ability to accomodate a large variety of flies. Most of all enjoy the experience of the purchase.
