Trying an EVOD on my Provari (510 to Ego adapter) and it's working really well but the draw is terrible! It's way to airy. There is absolutely no resistance at all. A piece of tape over 1 air hole helps but it's still really airy. If you cover 2 of the holes then it's a little too tight. I thought the EVODS were supposed to be a little tighter draw than the Protank 2. My PT2 is like tring to suck a golf ball thru a straw compared to the EVOD. Maybe exagerating a little but is this normal or maybe has something to do with not sitting flush on the Provari?
run, here it comes......
