Well Thanks for the replies.
The one reply stating that 70cm is sometimes the only repeater available (dependent on the area) is making me lean towards the 8800. That's going to make me change my antenna choice as the firestik is only for 2M (liked the idea of matching antennas but function is more important than form). We do a fair amount of traveling and I do end up in AZ, NM and NV a fair amount also. I should have stressed that a primary concern for me is safety, I want as many means of communication as possible. We often travel solo to areas that only get a few vehicles annually so having flexibility might be worth the increased complexity.
