I do have a bike with a triple that I rarely ride, not due to the triple. I live in a very flat area and do not need extremes for either the cassette or crank set. My favorite crank set up now is 48/36 for crankset and 13-30 for the cassette. If I travel and have climbs to do, that will pretty much cover anything I am likely to be riding. It is easy enough to switch out the cassette if the need arises. Also, my favorite bike to ride has a crank set that I can easily switch the chain rings to larger or smaller. In the end, is it worth the cost to you to give it a try
