Only thing with the micro coil is that I seem to have to squank more. I image that's because there is less cotton. Any suggestions in regards to a longer/thinker wick?
I'm not sure what the diameter of a T-pin is, but if its smaller than a 1/16" drill bit, you could try 8 turns of 30 gauge wire on a 1/16" drill bit which will allow a slightly thicker wick to hold a bit more
juice. That makes a 1.6 to 1.7 ohm coil. Then cut the cotton wick to length so the ends of the wick end up around the base of the posts. I get maybe half a dozen good toots per squonking with this setup. Of course, its not a cloud maker like the lower ohm
coils a lot of people are using, but it suits me fine.
Here's a pic of a similar setup. Maybe too much cotton on the RHS but gives an idea. Be careful when you screw the cap back on that the wick ends stay put. Pull the drip tip and eyeball it to be sure.
I don't know if this will work better or worse than your current setup, but if you are looking for something to try, its worth a go.
