Many of us started furling because of Kathy Scott and we know that Parnelli has taken furled leader formulas to another level.
I thought you all might be interested in a comparison of Kathy's original DVD formula to what Parnelli's "Big Tapered Leader Formula" would recommend for peg spacing.

Kathy's...18" - 42" - 66"

Parnelli's...30" - 51" - 66"

Do with it what you will.

Oh, and I want to credit Karel Gol from the Netherlands for providing me the writable spread sheet to get these figures.
