Hey guys, I currently have a 3000 psi draxxus tank (alloy). I am probably gonna get an ego 9 this christmas, and people have said that for bigger tournament play I need around 4500psi, and a lighter tank so that my gun doesn't become back-heavy.
Well stako is your lightest option but sadly only has a five year life span,
then after that i'd say not that greater difference between the other that i notice anyway, i use a dye throttle 1.1 -4500psi and love it, but as we all know its a personal preference .
Take a look at a 1.1L Fibre Wrapped Draxxus Tank, they're slightly shorter then most tanks, but the Stako tank is the lightest. But as he's said above, it only has a life of 5 years. You can't get it re-tested!
