cockers do NOT suck, and they never will.
You can have your $1500 DM5, and it wont make the least bit difference.
A cocker is fine for speedball, the extra range is a godsend if you need to drop a few shots on a backman to let him know you see him. Im not saying cockers are the best gun around, but skill is the deciding factor to any sport. I have seen the guys with their angels that think they're all high and mighty get taken down by a couple of kids with spyders. Sure the gun counts, you couldnt survive speedball shooting some brass eagle or somthing, but at a certain point, they all do the same thing: shoot paintballs
