Well I don't know how much a dropout phantom will help your ego skills. The basic things like thinking on your feat and movement will get a little boost regardless but I don't think using a completely different gun will help your abilities with another. If you want to get better at "gunfighting" you should be practicing with the gun you are trying to improve on. I say put the pocket hopper on the ego and limit the bps if you want to improve. If you just want to play pump then use a pump gun.
