For me the tv4 was a heavy rolling piece, OOB 2000 w polish it cleared the heads good. Hada 4.5" pin under it picked up nice at mid lane with a nice backend reaction. I put about 100 games on mine and scored real well with it. Changed it once to 2k abralon new pad and rolled even heavier and of course earlier.
Depends on how bad you need the piece, probably better options since it's around 4 years old , but it was a unique ball. Hope this helps.
