Which brand & model of walkie talkies for my "spotter?"

Having made my living using Radio's of some sort,I stick to Motorola/Cobra and Midland which I have found to be the most reliable.

We use ours alot including backing in tight spots but more for when we take two vehicles to the hills with the windy/narrow back roads with the front vehicle letting the tow vehicle know in advance of upcoming events and or breaks in driving.Works great and way less chatter than a CB.
