Cash...I moved to Squonks a while ago...I still have my nostalgic Tubes/RDAs that I will never get rid of...but I haven't dripped on them in months.
Plus the greatest thing about them outside of being able to juice up without dripping...they weigh so much less...sure they are wider, but yeah, 100+ gram difference easily in weight. Plus its nice when you're driving any amount of distance you just do a press on the bottle and take a rip
If you ever want to try it...since you like to go low and cloudy now, try the 528 parallels when they hit the China sites...they will be "unauthorized Authentics" at half the price... just the same as when the Goons that caused the shit storm for 528 did on FT and 3fv.
Plus you can build nutty low on parallels without really having to worry about if you're pulsing them to high.
Purge also has a squonk mod
