Well... The problem with running wick all over the place is how long the juice has to travel before it gets to the coil. If you have the wick go across the deck and back over, then any juice in that extra part of the wick has to work its way down the wick, past the deck again and back up to the coil. It might work against you since that extra wick might pull some juice up before the GOOD part of the wick (between the deck and the coil) gets juice... all that wick has juice moving away from the coil, not towards it.
That diagram that you see in the Kayfun 3.1 instructions? That, to me, is the most efficient way to get things built out. Ideally, the only wick that you have is on the deck (therefor getting saturated when juice feeds in) and as direct a shot to the coil as possible. It's the same way for an RDA. I've seen people pack the hell out of the deck with cotton or silica, with the expectation that the RDA would hold more juice. It might hold more juice, but the wick that's in the coil might run dry before that juice 4 miles away gets a chance to work its way down.
Now, with 100% VG... the viscosity might work against you, wicking-wise... in those cases, you might want a larger coil and a larger wick diameter (and a little looser I would guess) so that you have more wick to suck up that juice... but you should still keep the wick between the coil and the deck to a minimum.
Just my thought on matters.
