12 Revvy w/ x-board. The revvy is OK for most guns, but the Halo B blows it out of the water.
Angel Impact IR3 w/ silver to black dust fade, SS Freak, 14" AA tip, or Ti Boomstick, Cobra bolt, SS buttons, Cobra fang grip, 68/4500 new style MaxFlo, Smart parts drop.
The Halo B is very well made and durable. It appears to be made of thick plexiglass, instead of normal plastic like most other loaders. It's very smooth working, and its "eye" is very efficient and can tell when a ball is present, Unlike my 12v Revvy which would spin a lot, even when it was full of paintballs. The lid on the Halo B snaps down nice and tight. Some guys get mad that the neck is too big and has to be sanded down, but I appreciate the fact that it's made like that, so that it will fit tight inside different feed tubes. If you have a Dremmel tool with a sanding drum, you should be able to sand it down to size in no time. It only took me 5 minutes to make it fit inside the feed tube of my Angel. This is a great loader. I consider it the best! I got my smoke Halo B brand new from a dealer on Ebay for $110 shipped.
It's a little heavy with all the batteries in it. I wish that somebody could make a way to hook Intellifeed to it; It would be a lot lighter (no batteries). Don't use paintballs with black shells. The "eye" won't see the ball, and it will keep spinning and burn up the motor (so I've heard). It's a little big because of the big motor and the way it feeds. SOmetimes the little rubber on/off button is hard to push with gloves on. The button could be bigger. I wish it held a few more paintballs. Some guys complain about having to sand the neck, but at least you don't have to wrap tape around it to make it fit tight in the feedneck. Tip: If you accidentally sand off too much, you can get some Superglue Gel and put it on the neck and spread it all around with something, then let it dry. It will add a little thickness to the neck and make it fit tighter.
It's a great loader. Smooth and Quiet. Very well made, and Very fast! It always keeps the balls coming. This is a big step up from a revvy. Definitely worth the money. It comes with a good warranty. Odyssey has great customer service. This hopper should last a long time. The belt drive is great. It doesn't double feed like the Halo A would on some guns. It's a little big and heavy compared to other loaders, but it's fast and reliable. I wouldn't use anything else. But watch out for the new loader that's coming out, called the "Corkscrew".
