RussianHill,
I just had this conversation with my brother in law last night about gearing for his bike!
I've been riding an FSA 50/34 compact double for over a year now. My training partner rides with a triple. I must admit that while I like the compact double there are times when I wish I had one more gear to go to on a long steep climb at the end of a 4 or 5 hour ride!
Since you are just getting into cycling after some time off I guess I would recommend the triple to start with. The weight difference isn't probably going to be a big factor and having more gearing options on hilly terrain could make your ride more enjoyable.
Whatever you choose, enjoy that beautiful bike!
