Not all regs have the same flow. Different brands have different flow properties within their given pressure. That's why some low pressure tanks/regs such as Crossfires, Ninjas, and CPs typically never have problem with shoot down though other lesser quality tanks such as Pure Energy and even Throttles can have some issues.
