Brett, the spinn you're running on your 6.0 is an F18 spinn made by Performance Sails. It is FAR more developed than the old E/P spinn on your N20. The N20 is a bit fuller and the draft is a bit farther back, so it is like comparing a Corvette to a Radio Flyer wagon. The two will never perform the same but each have thier strong points. Not sure how old your N20 spinn is but they have evolved a little. When you're in the market for a new(er) spinn, I have one that has two takedown patches and very little use for sale.
