I don't think the direction of the winding is signifcant. I have taken the relay out and put it back in so many times that i'm sure it performing the same (or at least very similarly) in both directions... there is no noticable difference.

Looking forward to hearing your friend's results Aaron! would also love to see a scope shot if anybody gets similar results!

Ren - I would like to try and take out the resistors all together and just use chokes but at the moment I can't get the right value...I only have 2 of these coils and if I put them both in series I can't get the reistance low enough to get to a sweet spot... I might try taking half the windings off one of the coils...
