so when ever i play its either with a x valved mag or a pump mag...the x's never have a problem keeping up with my fingers and the pump is just that, pump and shoot...but when i played with a classic valve w/ level ten it seemed like the valve would not keep up with my shooting...i would get about 3 or 4 quick shots and then the valve seemed like it was starving for air? about 850 output tank(same tank i use on with my x valves)...i know the recharge rate is way slower in a classic but is this the norm for the valve?thanks
