i dont know what the advantages of flipping it around necessarily are, you just dont have to wrap it underneath and i like that. and for locking it i just put 1/4 inch washers on the posts that hold tha bar and springs, they wont fall through because it gets bigger... and i just tighten it untill the bar is all the way down on the plate, i dont need space underneath the bar because i flipped it around. it works perfectly
