I have both the Bite and the Dynamo. I've been so impressed with the Bite, I have a second NIB in storage. The asymmetric Gas Mask Core in the Bite is extremely versatile, and with the right drill, you can generate some real impressive backend.  

The similarities between the Bite and the Dynamo are remarkable. The difference I see is that in OOB, the Dynamo can handle heavier oil. As an example, on our fresh higher volume league roll-off condition, the Bite was blowing past the ideal breakpoint. I pulled out the Dynamo, and I got a look others were having a hard time finding.

On the other hand, on our shorter PBAX patterns, for me the Dynamo has been a little too much off the dry, but the Bite gives me a more controllable breakpoint/angle.

These comparisons are based on OOB covers. Altering the grits on the two balls would probably change things. But my sense is that the Dynamo is the better potential oiler between the two. For right now, I'm going to keep them as a 1-2 punch. The Bite for shorter patterns and the Dynamo for longer and/or higher volumes.
