I need a tip top for a graphite 2 wt Redington CT which is now a 7'4" rod. It's a really small diameter blank up there at the tip of that 2 weight, but I don't have calipers or anything to measure. Any tips on how/where I can get the right size tip top to install? And what is the correct way to mount it, or I guess I'm just asking what's the right adhesive?
