Style wise, the cocker has a lot going for it with all that crap on the outside. From street rods to choppers, lots of vehicles profit from visible external mechanical processes. In fact, if you were to get to what people like aesthetically about cockers, I bet that smacking back block would be high on the list. All the crazy looking tobes and bits up front wouldn't be far behind.
Sure, it is impractical to clean (even harder to clean while a game is going on around you
). Still, I think especially to transitional players (that is players just getting into competition after having been committed rec players), cockers have plenty of relevancy. These are the same players who see wiping as a moral issue primarily, who are open minded generally about what equipment is competitive, and who are skeptical about the fashion that sweeps through paintball any given year. For many of them, the long term popularity of cockers is reassuring, the enormous field of aftermarket options is a plus, the obvious working system is reassuring, and the cost (especially used) of most cockers is helpful.
I don't find it surprising that no pros team will shoot cockers next year, but I don't expect them to go away, either.
