Can a Promaster Monopod Outdo A Tripod For Long Exposures?

Let me preface this piece by stating that Promaster never stated that their air-cushioned monopod could ever be a replacement for a traditional tripod. Nor did they state that this could be as good or better than in-camera image stabilization. But with mirrorless cameras these days being so light in weight and claiming in many cases up to 5 stops of handheld image stabilization, we figured we'd take the Promaster Air Support Monopod through some unconventional tests.
