Well...right fee is alittle slower because gravity has less of a chance to help out....the other reason, is because you cant fit the Eblade antichop eye on a RF cocker....thyats why I suggested a Warp and HAlo...coz then you can set the grip to 20 BPS and have no worries...or, as has been said a Q loader...but, these kits work out expensive when you think, you might need 10 pots for a game....blinding system tho...emptys a 100 shot pot in 1 second so about 30/40 bps when on a marker, depending on the setup.
