>>10606128There is no need for an extra stand in most cases, you can absolutely balance a kit with super huge weapons without issue. The problem comes in when you a, don't have a stand on the base kit, and b, have the kit in an extreme pose not accounting for the balance of the weapon. Sometimes you can cheat too by using a msg joint to connect the weapon to the kits body.
Out of curiosity, what weapons are you talking about?
