So, my favorite build so far is a standard spaced coil. 6 wraps of 22g wire with a 5mm id. But, the key to taking full of advantage of the build is making sure that the coil is even with the top of the positive post on the deck so that coil can utilize all the air flow from the top and coming from behind.
ps i also have been thinking of drilling out the deck so i can set up dual coils(1 on each side of the post)
