Okay here's how I'm gonna break this down. I have owned both an etha and a reflex rail, and am about to purchase a drone.
1) the etha is the least smooth and also the loudest. That being said,its by no means a crack or a jackhammer, its a fantastic little gun for the price. I didn't like the panel grips, little thin for my taste. The trigger was alright, nothing too ooze over. Its definitely a great all round performer
2) the reflex rail is probably one of the best feeling guns around. The grip and ul frame on it is fantastic, the trigger is nice (some say too stiff) there's rubber on the reg and the macroline is streamlined. The shot is a nice spool chuff, smooth and quiet. However, if your field fills to 3000,you have to pay by fill or you shoot lots of paint in tournaments, DO NOT GET IT. The efficiency is piss poor. I was stretching it to get to 5 pods on a hot 68/45.
3)The drone is the conclusion I have arrived at, being able to hold it recently. The trigger is nothing to brag about, but its certainly not terrible. Its just shaped a bit oddly, less rounded at the edges. From all I've heard its smooth as if not smoother than the reflex. Its a simple design and it works
Also they fixed the psp mode as of January 13, so if you buy a drone new or one that's used that was purchased after that date, it will have the one second timeout
Thanks. This is very helpful
