Yeah from what i see the give on a prodigy is not really going to do much. I mean yes when you run it and your finger is able to push the nipple back i see that... but most rotaries are running fast and seem to rely on the safety of the crank wheel to pull back the needle and not the skin like a coil... My RW I.D. in my opinion seems to work very well with no give. I think the Centri design is a rotary with true give... and I hope that kind of technology is perfected one day because it is a truly smart way to make a tattoo machine hit, and the fact that you can adjust the stroke on the fly is super sick. It sucks that the centri's failed pretty bad from what i hear. I hope he hits a muthafuckinhomerun with the new one.
