Rpenmanparker is giving you good advice. The main advantages of a triple is staying on one ring for long periods of time and not having to surf the entire cassette to find a gear. That is why the overlaps are there. Once you get to an overlap then you can shift and stay on that ring for a long time going up or down as necessary. You ride in ranges and loops. Ride on one ring, up or down 5 or 6 gears then you shift to another ring. Ride on that ring up or down until you run out or gears one way or the other. Then shift again. You may go back to the ring you were on. Then the same loop/sequence repeats itself. You also get to keep the standard double which is great for general riding. I may go a week or two without going on to the granny. I also have rides that the 52 big ring is seldom used. I loop between the middle and the granny or the big and the middle. I have one ride that I made up a 50/36/28 crank for. That is a 100 miler that I'm on the 50 for maybe 25-30 percent. The granny sees the most action on that ride. I run 3x5-8. With 11 cogs on back you should be able to stay on a front ring for long periods of time. You might even go complete rides staying on one ring.
