I’m was a big fan of the GB3 and I’ve found this polished version to be just as good. I went with a different layout on this ball than anything else I’ve done with having the pin 3 inches from my axis and it certainly roles smoothly and moderately early. For my particular layout, it hasn’t allowed me to get too far left, so this ball is something to use on medium length conditions and with clean backends. The ball is very controllable so hitting it with a little surface can help blend out flat patterns early on.
