Re: What hopper would you say is the overall best?
Personally, I'd keep the B2 rather than spend another 100 bucks on something that will perform pretty much the same. That's 100 bucks you can apply to another gun or to paying to play.
Now, if you really wanted to spend some money for a different style loader, I'd go for the magna clutch drop in kit and get the RF for it, then it'd be the same as the pulse but for less money, but again, it's not going to perform any better than what you have already. It's just going to be able to be sync'd to your gun...
Of course, this is just my opinion - I was never a hopper hoarder. It's hard enough to choose which gun to pick when you have more than one, let alone trying to figure out which loader to use as well!
