Alright, I haven't ever thrown a Slash or seen it in action, but I read that it is a performance ball that rolls well in medium/heavy oil. I would advise an Inertia or Machine. You can check Track's website if you want to learn more. Another amazing ball is the Arsenal Artillery. However, that is a ball designed for just medium oil, but medium oil for me can be light oil for you (or your dad, for that matter).
