I have 2 shortys, and 1 baby, haven't had the chance to hook up the baby yet, but loved my shorty so much, bought another, then came upon a good deal for a baby so grabbed it.
Used the shorty on my very heavy stocked 180+. My next setup will be a 300g +, which I will be using a shorty, and a baby.
They perform 10x better if gravity fed
