Hey guys, I have found that while I do get good vapor production around the 12-2 oclock range on my cloud, at these settings there will usually be a bit o' green towards the top of the ELB around the edges even after several long pulls. I usually creep the dial up towards MAX in order to get to that part. Sometimes I drill a screw down into the ELB with my fingers which is a great mixer. and also helps But I find that when going over 12' on the dial, I start beginning to taste the metal screen, even through the hydratubes. When at max temp, it's pretty noticeable to me. Now I have tried taking the ELBs and soaking them in ISO. I also took another one and lightly roasted it with a butane torch. That probably helped the most but didn't eliminate the metallic taste I get on higher temps. Again, I don't notice it at 12. I start to notice it strongly at MAX. Also, how many back to back ELBs can people here ABV-Cache to completion? I am finding that trying to thoroughly exhaust the ELBs before reloading is really tiring my lungs out because finishing the ELB starts to take really long pulls at the end. The other night I had to take a 30 min break after 2 ELBs back to back. Any technique suggestions?
