10 ft. fast sink.
 

Hi everyone, hope you're all having a great weekend. I picked up a 10 ft. super fast sink leader to add to the end of my floating line. I've only ever used floating line, and could use some advise on what length of leader/tippet to add of the fast sink line? Hope to be using it with boatmen patterns in lakes this fall. I appreciate your help...thanks.

2-4ft matched to the size of your fly.
