IMHO, they're better than straight bar deads, no need to worry about form too much, and no fucked up shins. They do seem to hit the quads a bit more than straight bar does though. Bigger guys may have trouble fitting inside it though, I'm only 5'9". Zack, they can hold quite a bit of weight, my new gym has shitty one with the rotating handles, yet i still do sets of 8 with around 450-460. I do use straps though, the knurling on these babies will shred your hands (great for getting rid of callouses, i guess). I dont like em for shrugs though, not nearly as much ROM as a straight bar, at least for me...
