my halo is pretty pwp when i put reballs init, been told many ways to improve the amounts of jams BUT none work lol, used a gravity once my halo was doing my head in soo much.
Best option for reballs in a Rotor is the Seed Kit, few of our guys used the upgraded Rotors reballing today with no problems.
I have to say I had no problem with my standard Prophecy feeding reballs either.
