So I got the palmers QEV and added it onto my marker. Seeing that some people on this and other forums have had trouble with the QEV I made sure to READ before I bought one. After a quick look on palmers site I got the tube that was meant for both high and low pressure so if on the slight chance I decided to switch to LPA in the future I wouldn't have to fool around with my QEV.
The qev was kinda a pain to put onto my marker. Cutting the micro line was a huge pain but eventually I got it down and it works perfect. It is easier to shoot faster with my mech a-5 and I have not had any problems with my cyclone.
