haven't used a triple, but find 14 plus speed on double intimidating enough. You should be able to get a wide range using a double with advice from your local shop on the number of teeth on the big/small cogs. I use a double on local hills (Hocking Hills, Ohio) with no problem. Techie argument oppoing this view will be gaps in shift patterns, and less smooth shifting. Again, more sophisticated concern than my talent level warrants.
