The new colors are barely worth more. Its more likely because they are so new it would follow theyve been used very little and are in good condition and/or sellers think because its this year's colorways they can get more for them (which I wouldnt agree with but there are stupid buyers too).
But I run it with dye rotor which can easily feed 12 bps also if I just sit and pop off single shots 1-2 bps I still get chops. Might try buy some heavy duty paint and see if its any better
It's not a matter of the loader, it's the design of the gun. Without eyes it's going to chop if you shoot fast. If you're shooting brittle paint you're going to get breaks. The rotor also isn't gentle on paint if the tension is set too high. It could be one of those things or all of those things.
Youd be hard-pressed to get a chop using a force-fed loader. Especially a Rotor.
