well first of all, the matrix doesn't chop with a Trinity LPR b/c it is such low bolt pressure. It has less kick than an impulse (pretty much no kick). Operates at lower pressure. Faster ROF. LCD is about the same price as FF impy but E-matrix w/ bolt kit and Trinity is about $150 less than the FF impy and the matrix still works better, in my opinion. So..... there is a Matrix vs. Impulse thread in "Paintball Talk" check it out...
