Hey Loose,
Becareful with that Avenger, I had mine bcak then at 4x3 and it was a little jumpy still on the back. It didn't like oil that much either, the Silencer came out as a stronger ball. DP3 is correct on the KO Punch, dull cover, smooth roll. The Hex is being compared to the CrunchTime per a lot of guys, good roll, reads the midlane and arcing backend. Hope this helps.......
