i was going to go thru the entire thread but i was already LMAO before i got to page 2 and couldn't take any more of it. so, sorry if this has been brought up already.

but i just wanted to say that my 105 triple shifts way smoother than my 600 vintage double. could be lots of reasons for the disparity other than the fact that one is a double and one is a triple. but the 105 came with a bike i got on ebay and my first "upgrade" was to get a double (standard or compact) but after riding a few weeks i found no justification for doing so. yeah, it doesn't look as cool as a double and it does bother me a little bit that i have the extra chainring/weight when i live a pretty flat area, but as other have said, the weight difference is minimal and no problems with shifting performance, and it might come handy when i start doing some real climbs. interesting how in mountain bikes, almost everything is a triple (or a single chainring) and nobody cares about it.
