RE:Leaders: 60/20/20 rule
... where the 60% is split 60/40, the taper is split into three even pcs for drylines, and the tippet is one piece unless really long when I split the tippet 40/60. (anal)
For sink tips, I either go three solid pcs -or- split the taper into two even pcs to get the tippet to the lb # I want.
Every pc graduates down. Maxima makes it real easy - #test instead of diam.
