My Burgundy Hammer, bought because it was supposed to be a light oil ball, AND testing by BTM indicated it needed a lot of dty to be used successfully, was anything BUT a light oil ball.
I'd say it was/is a lot like the newer Cherry Vibe that so many people here say is so much stronger than it was designed and advertised to be.
My Burgundy PH, drilled a simple 4x5, was able to handle true medium oil in a very controlled manner with its stock polished cover. I wouldn't call it a control ball, like the Storm Tour Power or the Visionary Blue/Green Centaur, but it was very medium in length and had a very medium backend, as things go nowadays.
It turned out to be very good to handle wet/dry medium patterns on synthetics, which, in a sense, in a urethane trait, but its hook is not urethane-like at all. I'd call it mild resin, if naything.
However, when I needed it to handle light oil, I had to sand it to 4000 grit and then put a strong dose of polish on it. I tried it at 4000 grit matte, and it needed more in the nature of medium oil.
