So you're a power rider and can leap hills in a single bound. Must be nice. I'm a spinner, I recover fast, and have no trouble on the flats but hills are not fun.
I had a triple on my Giant OCR-C and took it off when I upgraded to DA cause I wasn't using the third gear, went to a compact double. BUT, I wasn't doing rides with plenty of hills. Picked up the Tarmac and it came with a triple. I thought about replacing it, but left it on and I joined a new group for mid-week rides that only does rides with lots of hills. On long rides, over 50 miles, that can take it's toll. So I use the triple when I absolutely have to. It allows me to pass stronger riders struggling with a double on the same hill in the same pace line. On a recent charity ride, I passed several who where off the bikes walking the last hill or two, bet they would've liked to have a triple.
That said, most bikes have doubles and most strong riders don't need a triple. I'll keep mine for now.
