Does anyone still need flying lessons? Don't forget to be easy on the throttle, this baby gets hot quick! All BS aside, the SR-71 has turned out to be everything that I expected and more!(a vape that I can pick up, turn on, get to where I need to be quickly, and move on!) The efficiency was noted by another user earlier, and I must say I agree, once you get the hang of it, I'm definitely not worried about wasting oil in it anymore. When I first got my Hurc, I put quite a bit(2-4g?) of oil in it to "learn" (not all at once) what I learned was to always have your buffer, cool properly, easy on the power, and if you fuck up, iso reclaim, and dump it back in!(almost tasted as good as the first time through) I found some oil in the bottom chamber and mouthpiece, both from over powering, but no worries it all comes back!
I feel like I am rambling now, but I wanted to share my experience with the SR-71, because I was extremely disappointed with the V1 Hercules, and deeply concerned about messing something up on the new one, but here we are finally! This thing will hit any way you want it to(wispy to nail-like), once you get the hang of it.
Keep innovating G!
