I have a 48x34 FSA Gossamer MegaExo on my Tricross. I miss my triple (52x42x30). I like to use all three rings, and I had a better range of gears, and it was easier to find the right combos when switching rings. With my double, I'm either spinning too much or pushing too hard a gear when I change rings. That's my two cents...and I don't race.
