I didn't read through all of the posts, but uh.. Why would you want them to be any bigger than they are? So when you go to to fire them they explode because they're inside a wall from their ridiculous size? Sounds functional to me!

I hope you see the sarcasm and the point I'm trying to make. It's not like the SB is at the forefront of combat and effective damage dealing anyhow.
