I'm with Houston on this one. On standard setups there is no real advantage to Neutrix aside from they won't short because they can't be easily pulled out but the fact they can't be easily pulled out can be a problem also. I watched a rack (not mine) come tumbling to the ground one night because someone tripped over a speaker wire and took the rack with them when they went.
That being said if you are doing FOH you should really consider Neutrix
