Ya i saw that one too but completely disregarded it as a working design, look at where the wick was, it might work very well thou, who knows.
Makes me want to grab one of my Visions and trim the wick to see if there is any difference.
Hmmm.... I might just do it.... Unless mindfield beats me to it
Anyways.
The only advantages I see to these is the cone type shape that would force the juice towards the coils. But if you don't tilt your PV when taking a hit I don't think it would work very well.
