Someone pointed me to that (or similar) a while ago. Works well for me especially as I've got a TiPX with 5 x 7 round mags. I'm considering investing in one. If you get one let me know and how it looks/works etc.
Hopper is fire lots and hopefully hit something. If you get hit you end up with lots of welps.
Lots of ballers firing lots of paint.
Magfed you'd be lucky to use 200 balls in a day. Much more tactical, team orientated and selective shooting. It's a great style. Just like real guns, you need to know your stuff as you'll be servicing you marker throughout the day during breaks to get the best out of it.
That's a modded Dan Wesson to take paint. If a revolver is your thing get a Crossman 3357. I have 2 but their rare. For me get a p99, glock 17. Their mag fed through the pistol grip and stand up to use.
