Both IMR’s were received today. Everything is in working order.



I have to admit the R1 Zenith is a little confusing/disconcerting with its vent mechanism that seems to nearly twist forever. The OG R1 is much more straight forward and controlled with its limited range of motion.



Instant thoughts are that the Zenith is a clear step or two below the OG. Zenith is a little, make that a lot... strange. The OG sounds much better in any configuration.
