I don't know anything about your e-cig, and I am completely new to this whole thing... but, one thing I learned fairly quickly like you was the vape and flavour was not so strong after a few hits - I realized I was filling my carts more often than wished & got more leaking than I wanted too (over zealous?). I tried dripping a couple of times, but thought that was sort of a pain, just like adding to my carts so I went searching for mods. After a few tried mods, I landed on the spring mod.. 2 days with the spring so far and I love it! Keeps the atty wet and each and every drag is pretty consistent & strong to the very last drop! I burned through my first test bottle really fast through trial and error, but since I added the spring, wow the liquid I'm going through is far less, and the need for an analog is down to a few puffs of one instead of a few whole analogs without the spring. Like I said I am new

Might be worth a try? I currently vape with the m601/602 with the spring in the vertical position instead and a PTB plug. No leaking yet....
