Halo B, Empire Reloader, The egg, pretty much any force feed electronic hoppers
Red to Black, Angel G7 fly w/ the DXS tank (ultralight), new ASA, RF chip and a smoke pulse
Speed, consistency, ease of access for cleaning purposes
none that I can think of, price maybee (expensive w/ the RF chip)
About a month prior I purchased a Halo B w/ rip drive and was extremely disapointed. I guess I just expected more from a hopper that costs over $100. Plus my halo fell apart all the ball bearings blew (isolated insident). Anywase I bought the Pulse at my local proshop, put it on my Angel, and played for the day. Let me say w/ the RF chip that thing rips. Thats all there is to it, It rips! You never missfire, no matter how fast you shoot this thing keeps up. It feels really solid as well. In addition to a nearly perfect hopper Draxxus threw in a removable drive cone, how bad a** is that. It is so easy to clean. If you have the money don't think about it, just buy it.
Other than a grand total of $170 for the chip and the hopper the pulse is a flawless loader. Consider this, you are paying $170 for a loader that will NOT let you down.
