I will probably get one or another compact, which ever can be maintained easier by some LBS, with the lowest gearing that is available. If the hills hurt my knees, then I will walk. It really is not about strength, I have enough of that. The issue is managing the strength so that I do not hurt my knees and then riding will not be an option. These are very helpful comments and I appreciate the thoughtfulness of all the questions and replies!
I think you can "future proof" by using BikeWNC's method he discusses in his post. By using a compact double along with a MTB RD you can have gears that are even easier than most standard Triple setups. I've been using that arrangement for several years and it works perfectly. The new 10 sp 11-32 to 12-36' cassettes also allow for a very wide range of gear inches.
