SP Ion. Upgraded virtue board, drop forward, Easy on button, Sling Trigger, Redz Body Kit, All american Barrel, Halo Hopper, Compressed Air.
No Chopping. Didn't have any sling in my shots.
Price i guess...but they're not too expensive and quality is worth paying for.
My local shop sells these for 50 bucks a case. I hadn't ever used them but last time i was there the guy offered to sell me 500 of them for 5 bucks since i had spent so much money there. i took them home and played some woodsball all day with my buddies. I never chopped a ball and was very accurate. That could have been my barrel but im going to say it was a mixture of both. After we were done i decided to empty my hopper with some target practice. I stood about 50 to 75 feet away from a light pole by my road and shot. I never missed and in the 75 to 100 balls i shot i put a mark on the pole about 4 inches in diameter. This proves to me that they were very consistent and accurate.
I would recommend these to anyone with an ion. Just because thats the only thing i've used these balls with but im sure they'll do fine with another marker.
