440 .509 292 Iron head monsters

383 with that cam was a absolute dog till I bumped it 4%. The 284/484 I had was superior till I bumped the the 509. TM6 with 750 double. I gained back all my bottom with little to no loss on the top, 906 unported heads. I loved and still love the 509, just have to set it right!!!! There are better options out there but I am a purple kinda guy!
