Vulcan3 or Uragan in .30 for Light-Medium Slugs?

I'm getting ready for my next air gun. I'm very impressed by my Vulcan2 and want to continue my AGT experience, this time with a slug gun. I've been debating in my head if I should get a V3 short, V3 Long, or Uragan. I feel the V3 is a great size but not large enough for great slug power. I feel the V3 long is too long for my liking. And the Uragan is the right size but not sure if it can get flirting with 90-100fpe with good accuracy?

Could some of the early V3 owners post their experiences with it in a slug configuration? Or, some of the Uragan owners tell me the accuracy and power with slugs?

I appreciate all your help!
