The high 5 does engage a lot firmer than the rps. The rps is almost stock feeling. So smooth and not a sound made. But the rotating mass of the rps is huge. It's a heavy beast. I would still be using the high 5 if it was going to be able to hold my power goal. But it won't so on the shelf it sits. I love both of them. The rps more so for street driving. But can't beat the cost of the high 5.
