My friend who i play the odd walk on with uses an impulse and they are a very good gun, but heavy on gas,paint and balls obviously due to electro firing, buti am not exactly sure that they are so mutch of an upgrade. The autocockers are more accurate in my opinion and a lot better value, but i suppose it depends on the style of your play. I play with a 2000 autococker with a 12" boomstick and an eclipse blade frame,this seems to fire fast enough, the long trigger on the eclipse frame helps. I,m happy as larry with mine and surtainly wouldnt chop it in for an electro unless something really special came out.
