Ah, okay, thanks for the answers. I thought people were modding fill holes to eliminate the need for syringes.
I can make it through the day with my 3ml tanks, but I carry spare juice anyway in a 6ml bottle, and can fill it if need be. I definitely don't want to carry a syringe with me, and the long-spout or syringe-spout bottles are unwieldy.
I also found that with the 1/4" screw I had to shave it down a bit, and now it locks the carto in place as well. The J-tank is tight, but now it's locked onto the carto and won't budge. I think I'm going to mod the tanks I got in the co-op the same way.
