@cracourax: The feed hole is at the bottom of the second nut on the positive pin. The second(lower) nut is changed and has cutouts to let the juice through. The liquid will reach the coils directly, excess goes in the well - at least when the coils are in the correct place. The V2 does not drain at all.
@Spydro: unfortunately, no. The V1 positive pin is longer than the V2 pin, so the V2 BF kit won't fit.
The Origens (and an RM2) are all I am using anymore. They really are that good on a bottom feeder. But I also know of a BF enthusiast who does not like them at all. So it's the marmite thing again =)
