Totally understandable guys,i really appreciate all the good advice,and years of experience,which has made things much easier.I'm glad to know in advance if something does or does not work,instead of finding out the hard way.I'm running MPI switches,and im debating on a third switch and battery,ive heard argument from both sides,im sure it would'nt hurt to have a little more safety,but it will ad some weight,so im still undecided,i have a extra switch and battery if i decide to go with it.
