How much weight?
I have 4 weights-2.25#, 1.5#, .75#, and .50#. For thread leaders and 6/0 Uni, I use the 2.25# weight. When I am furling 4# floro or 2# mono, I use the 2.25 and the 1.5# weights together.

How did I decide?
Trial and error. Not enough weight, too loose of a furl. Too much weight, a leader that will not "relax" when you take it off of the board, or breakage before the furl is completed. I try and keep detailed notes for the material used and the weight needed.

Do you furl to just pigtailing?
Yes, this is the goal for me.

Here is a picture of my weight system on my current board...



Remember, YMMV
