I want to thank everyone who participated in the thread.
After yet another blow-out (same tire) on the ride home last evening, I'm forced to make a move a couple days earlier than intended. I'll be stopping by the LBS tonight to discuss this further with them. I'm now much more informed than prior to starting this thread. Your comments have been enlightening and a catalyst for my own research. Thanks again.

I'll follow-up after the new tires are on the bike.
