Thanks to all that have offered their opinions and experiences. As I suspected, there is no one definitive answer to whether one is best with panniers or a trailer. Like so many other options, its personal preference. Though I was leaning toward a trailer, after reading all responses, I'll probably start with rear panniers and a handlebar bag for a few short tours. If I have the opportunity at some time, I'll pull a trailer and see how that goes. Again, thanks to all.
