Bottom line from you experts - I'm setting up an outdoor home gym, with limited space (and limited availability of equipment). I will be working out alone most often, so I use the spotter arms at the gym if on a stand. Is it really that much more risky to have a stand, such as the Rogue SML-2 Monster Lite, compared to a rack, such as the Rogue RML-390F or the SS rack? I want to be safe, but don't know enough to assess the risk.
