Re: Need advice on rigging fly rod
Rod repair is generally difficult to impossible. It sounds like you may just need to put a new tip-top on your rod at the point where it is broken off.
You'll need an 8 weight line (aka WF8F), backing, a 12 lb 7.5' tapered leader, and some other stuff.
Frank's right, consulting a fly shop would be your best bet. The search function on this site will uncover lots of info for you.
