Been building on my rda's for a while now and still watching others do their own build on youtube. They always say "not too tight, not too loose" while tugging on the wick. I've always wondered how much force is that? So, for your perfectly wicked coil, whats the minimum number of coins or grams does it take to pull the wick out from the coil? or how much weight can the wick hold before it slips out from the coil?
