A lot of people use Cockers. Strange and Aftershock come to mind immediately, along with the hordes of Am A and B teams that thrive on them. I almost would say don't forget the RT, but that isn't nearly as big a factor in the major tourney scene as it perhaps could be, in fact now that Jax Warriors are shooting Emags I'd say it's almost negligible. Though it doesn't have a huge tourney prescence because of its comparative rarity, I like Sovereigns a lot, a gun which in my opinion should have gotten to be at least equally present as the Cocker, and if given the input into design improvements that the Cocker has over the years it should have been the dominating non-electro of the market.
But on the other hand, I've been without an electro about as long as I can stand. I went from a Mag to a Shocker to a Cocker, and much as I love mine and won't ever get rid of it, I don't want to go much longer not having my own electro around for those days I just crave one, which do happen half or a little less than half the time.
