Personally, i dont think it would hurt if you added a tiny bit. I wouldn't go crazy stuffing it in there, and i wouldn't just not put anything in case of leaking ya know. What i would do is take a thin amount of the wick thats in your coil and find a way to run it around the center block and outter wall so the juice feeds from both sides. But that's just me, i would play with it and see what works best for you.Would wicking it on both sides work in single coil mode (just to hold juice)? I prefer single coils since I don't like to build below 1 Ohm at the moment. Single coil on my Magma is great since the juice well is basically in the middle, but so far I've only tasted juice on the Hobo I have, but was just curious if putting some cotton on the other side would hurt wicking.
