I have been messing around when some builds lately and was just wondering about a few things. For example I am using a Tugboat on an authentic Manhattan. I have two 28g dual coils. 6 wraps on a 3/64 drill bit. If I inhale very strong and hard for about 5-6 seconds the clouds are huge. I see a lot of people hit there mod for about 3 seconds and the cloud production is huge. If I made a build with 22g dual coils - 6 wraps on a 3/64 drill bit would I be able to pull on it for 3 seconds and get about the same cloud production or more than on my 28g. I have drilled my Tugboat out so the holes are now 1/8 on each side and I have drilled out the center post to accommodate larger builds. Any suggestions would be greatly appreciated.
