Hip, as you know there is nothing wrong with the triple. Get it if you want it.
If you're really wondering about a compact I can tell you that I have grown to love compacts. I have ridden a few different ones over the last 2 seasons and insist on riding one up in your neck of the woods. It is plenty low enough to climb Blue Mounds, etc. and I have yet to lose a race because I ran out of gear on the top end.....
I think you'd love a compact. In general I personally feel that Shimano compacts shift better than triples. That's the reason I would switch...not because of weight.
Just my $0.02.
