Re: Will Abel Creek 1 LA hold a WF 4wt line?
They recommend it for up to 3 wt. I'd go with the 2. You can use any backing you want. Not sure how much, just put the line on backwards first, wind it on then attach the backing and reel till it's as full as you want it. Strip it all off and put it back on backing first. Works every time perfect first try.
