Definitely safer for dumping the bar overhead, but that is very dangerous lol.
It seems I also use the low bar position, yet to decide which grip I prefer but haven't yet tried the suicide grip anyway; thanks for the input though, I'll be sure to note how the shoulders respond to the different grips.
