Okay, with the combined advice of the Plenty experts, I've managed to dimple the screen [is there a nipple making tool preference?], crank temp up to max, and have a bit more patience. I am beyond pleased with the results. THANK YOU TO ALL
For those who said caps don't work, it just took me a bit of work, but they effing work. I forgot what pure convection tastes like, and how high it makes you [and normally I'm okay with just getting even]. I am just beginning to learn how to use the tremendous amount of stored heat. I've been I'm working on a single, heavily packed cap [.2+], finely ground, and it's providing taste vapor for many, many hits [seems like half an hour or more]. I did take one long slow draw to start, and it seemed to heat sink it. Seems like there is very little downside to the extra metal in the bowl except the bit of extra time it takes to heat, but once it hot it may even add to the vaporization effect.
This is some of the coolest vapor I've experienced to date. The taste is what I remember pure convection is supposed to be, and I seem to get smacked in the face with each toke. I love that I can just let it sit for a few minutes hit the switch and BOOM, another fresh bunch of hits in a minute or less. I'm learning how to play with the Plenty and loving it. I am very, very happy right now.
Time to try and digest some of this thread. I'll keep you posted.
EDIT - capsule still goin...
