k so i just took the time to read through every post, I am a PTB pro, I have had great success and tried ab every PTB mod out there, the shredded works the best for me, but does leak some times. and isn't always consistent, when it works right, 15 drops, vape till its dry, but more often then not it doesn't when im at home i drip, best way to vape IMO, but at work I dont have the time to drip, (i spend alot of time driving) ive come up with my own ways to solve the leaking problem,(usually keep my 510 mouthpeice down when not in use so that the liquid doesn't roll out, only problem with that is when i go to vape the top is dry and I have to pack it to get some juice, and that can lead to leaking,
Since no- one has tried it, I will, today I plan on getting the HOT sleeve (whatever) size U for my 510 ill get back to you, once ive mastered it and let you know my assessment
