My local shop owner let me shoot an Etha recently and I was actually impressed. I own an Ego11 and a Geo 2 and use them both extensively. Using those 2 guns as a point of reference, I would say the Etha shoots like a mix of both guns. As other players have pointed out, there is a little bit of a "clangy" sound as the spring compresses and decompresses. However, it is not any more noticeable than the open bolt of an Ego clickety-clackin' back and forth. I would say it kicks about as much as my Ego 11 the way I have it currently set up. Other than that, it performed pretty much like my Geo2 in terms of sound signature and flight path (I've always felt my Geo shot a little flatter than my Ego = perception). Now that there is a tactical body kit out for it, I've been seriously considering picking one up for scenarios. I just wish I knew more about its efficiency...
Political correctness is nothing more than the belief that a person can pick up a turd by the clean end.
