Re: New Here and Need Some Line Help
For the 3 and 5 weights, use a standard weighted line like a SA Mastery Trout.
I'm assuming that you want a floating line for your 7 weight. In that case, I'd go with a 1/2 weight overlined line like a SA Mastery GPX. It will allow your rod to load more with some big ugly wind resistant streamers or bass bugs.
As for welded loops. If you don't want them, cut them off.
