Interesting. thanks for the link, light weight
full cage is preferred, but the problem is that it must go in the garage where the trusses are only about 2.1m above the ground and the spacing between them is only about 1.5m. there's enough room to get the cage in there, but it will only go in 1 particular spot. if for whatever reason it can't go in that particular spot then there's nowhere for it to go... that and the couple of hundred dollars more are a bit of a disincentive. enough to make me consider the alternatives.
hamburgler: i kind of agree. i currently have a squat rack which has safeties built into the frame and it's the same - i have no faith that i would hit that safety if i were to fail a rep squatting. benching is a whole other deal though and i think i'm more likely to fail reps benching...
