In case anybody is still wondering about dripping with the iGo, I've been playing with a few options. I've tried a 901 atty, but I didn't care for it. For some reason the draw is much harder with it as compared to the standard iGo carto, so I didn't feel like it was a good test of the
juice. If you're willing to sacrifice an iGo carto, you can pull the filler out and drip right in. That seems to be the best option. Otherwise I've also ordered an 808 dripomizer and pulled the batting out. That also works nicely. Or, just order a pack of the 808 G5 clearomizers - It gives you a larger test that's basically dripping without having to drip a couple drops after every few puffs.
