tried my M4 for the first time today....the sail has two separate tack pulleys.... ??? one was black..the other SS. didn't know which one to use. does anyone know why there are two ? maybe I should have read the instructions....but they blew away in the wind. btw...sail is awesome.

ok...nevermind. someone explained the extra pulley tack.

Severne sails have had the 2 black and 2 stainless for a long time.
So why and what is the answer?

Supposed to ise the severne triple block pulley extension.for more purchase on the down haul b/c of the high tension. I was using my duotone power xt extension (with the built in crank).
