UPDATE:
I know I said I didn't care to tinker with this, but after nearly going postal over wicking and coiling my DiD, and watching PBusardo's video on the BCC's, I decided that fiddling with this can't be any more difficult than a Genesis atty.
So, after removing one of the (short) top loosely placed silica lengths from the build, it's a totally different beast. Now, it vapes quite nicely, although the occasional primer puff helps.

Next I'll try removing one more of the three extra little wicks to see if that'll help more juice flow in without flooding it.
