Which one to choose? The b-112 launcher or the b-99. I would prefer the one that is more durable, and more powerful.

i would go with b-99 but if your looking for durable you should get b-112 they are more durable than string launchers they often get jammed or fray but they give power to make for it so basically b-99 is power and b-112 is durable

It would be better to use the sword launcher or a string launcher
