I have 2 horizon solids one drilled the same one of them with a weight hole added to it, i also have the new odyssey drilled pin over ring and mb just right and below the thumb. For me the horizon's are 4 1/2 x 4 and the odyssey is 4 3/4 pin to and the mb is about 4 1/4 inches to pap.
They do not roll alike at all the odyssey is earlier and with the drilling i have flips very hard off the dry boards, very very strong ball more ball than the lane g-force or a Total Nv i have at 1000 polished. It was a toss up to strength when i first had my Fury oob , the odyssey is more overall motion and the Fury oob was too rolly for my liking. I have since taken the Fury up with polish and now ruff buff and it kicks off the spot very hard now, i prefer it for a ball that handles carrydown with ease and hooks on medium on up with no problems.
The Horizon with the weight hole is closer to the motion of the odyssey, it is early and continues the whole lane with no quit. The one without the weight hole loads up and unleashes on the backend, about 3 feet longer and more skid snappy. Both are easily 5-6 boards less ball than the Odyssey, the odyssey is stronger than the battle also which is more of rolly ball for me than the Horizon's or the odyssey.
