You have the 34 now, on your current bike. I would say take it up some hills this weekend. Work out a manageable 1-2 hour loop within, say, 20-30 miles of home with about 1,500-2,000ft of climbing, and see how you do. If you need the 34 on your current bike, you'll probably need it on the Infinito. If you don't need it now, you definitely won't after. No need to take it up the hardest climb, just something that you find a little bit intimidating.
