Remember one thing - even if the Cocker don't spam out shots, it is still one of the most ACCURATE markers on the market. And it only takes one shot to nail someone. So what would you rather do? Waste 20 cases of paint and get eliminated, or get that sweet FIRST shot elim?
Of course the Cocker is a heavy mutha, and a pain to haul around all day. The ION feels like a feather almost, compared to it. But I'd rather buy back my old Eclipse Bushy if I did want something other than a Cocker.
