So I was trying to find an easier drawing atty to use on my 510 reo. So far I see that I can use a 306. But I see many people mention they are fairly finicky. One thine I wanted out of my lr510's was better flow. So I took one and enlarged the little air holes by the 510 threads. I seem to maybe get ever so slightly less vapor. But the draw is so much easier. Taste is good still throat hit is the same. I don't know I just thot if anyone was after an easier draw on a 510 atty I'd post this. Make sure not to drill too deep it's just a thin little wall u need to go thru. Any way if wanted hope it helps
