I use them for singles and triples on rare occasions, standing with a 16" cambered bar for a single 725, in chains way lower like 635, I prefer freestanding because I don't have to wedge myself under the bar to get going, really want spotters on these and I don't always go for pr's if I don't feel 110%-they are very hard on you imo. Also go wide stance one w/o and close stance one w/o to alternate.
