I have experience with the first one . . .the rogue one
That's made big enough to fit inside a normal power rack/squat cage, and be racked on J hooks.
For why I don't know . . . maybe doing weird Trap bar rack pulls, or pressing w/ it, or whatev etc.
Its real heavy empty and kinda awkward.
The amount of steel, welding and hvy duty design in the rogue bar makes the cost comparison the Gerard and Hampton seem like a joke.
Those seem pretty crappy/wimpy for being about the same price as the Rogue One (see what I did there).
