Hopefully some of you guys make your own sinktips from fly lines to fish off the end of your spey or Shooting head lines.
Currently I make them for my 10 weight (spey) rod from DT12 lines and they are great. Simply use some shrink tube and a hair straightener to melt loops and cut them to 5ft, 10ft or 15ft lengths.
I am keen to make some for my 8 weight Spey. Does anyone have a formula for the weight of the line I want to be cutting based on the weight of the head I'm using? I know there are skagit formulas out there but this is more like posh poly leaders and skagit formulas are not going to be the best to use.
