James – Your original question related to the merits of compact verses triple so all these macho threads are of little benefit!
The compact and triple have a similar range of gears and are both great for those steep climbs we don't have in GB.
For fast road work I find the 34/50 of the compact too big a jump for fliud changes without compensating by changing up/down at the rear.
Personally I prefer the triple as I can ride it just like a 39/53 double which I find easier to maintain a more constant cadence between front ring changes. The inner ring can be kept in reserve for the really steep bits.
Hope this may be of some help.
