I recently ordered the Rupes Bigfoot from DD. I'm transitioning from a PC to the Rupes. Over the last couple years I've gotten comfortable with the PC and want to get some feedback on the transition or adjustments I'll need to make. Per numerous Youtube videos with the PC, speed 3 to spread, speed 5 to polish, z pattern, alternating, until polish breaks down. Is the process the same with the Rupes? I watched their Youtube video and the guy is going all over the place, without any real pattern...I'm assuming this isn't the route I should go when using it. If anyone has experience with the Rupes, I'd appreciate your input.
