Got the flat taper strung on reel and added xtra fast sink tip. ? On how to smooth the transition. I could hear shrink but it’s sort of a bump. Could retie with a lighter line between then heat shrink. I’ve heard various adhesives, etc. I’m using a tight version of a loop to loop between them. I don’t really want the joint to pivot so to speak preferring a fairly rigid joint if that makes sense. I may have to go to a slower sink but won’t know until I try.
