Hi guys. I currently own a Proto Rail 2011 but have recently been offered my mates Etha for £180. The marker has only been used a handful of times so is in very good condition and only had a few cases of paint through it. I was just wondering if this would be a worth while upgrade from my rail? I know the Etha has the on/off asa, two piece 14" barrel and clamping feedneck, all which I don't have with the Rail but would it be an upgrade in terms of performance etc? Cheers
