I don't know. I am going to be converting my bike from a triple (52,42,30) with a 12-25 9 spd to a compact double (50/34) with 11-27 10sp and think I will actually be gaining gears while limiting my shifting. Now that I know how to properly shift my triple I find there are a bunch of combinations I don't use and I am shifting onto the small ring sooner and more often to keep revs up and maintain my cadence. By going to the wider ration compact double I will have more top end and the same (are darn near it) bottom end plus less shifting from ring to ring. With 10 on the back and a compact double I think it could be the best option.
Edit: ok maybe gaining gears isn't the correct thing to say. I guess what is really happening is I will be loosing duplicated gears.
