If I had time I'd rig up some tests on a breadboard, but since I'm traveling that's sort of a luxury I don't have. > Include vias so d and s have tracks on both sides of the board, and/or > solder wire on top of the tracks or heavily tin them.

I'm trying to stay away from having to solder wires on top though. I am curious to see what interesting ways I can use to get more track width once I get to the board design. Thanks!
