Has coddling tendencies.
I think this has been asked and answered several times already.

Seriously though, I discovered that many of the gear combinations on a triple crank are duplicates of one another, so what's the point? The gears you find most useful on a triple can be found on a compact double with a wide range cassette. Less weight, less shifting, same gearing. Want proof? Experiment with Sheldon's gear calculator.

I read an equation somewhere once that would determine whether you needed a triple or not. Something like:
Number of hills x average grade of hills x total distance climbing / rider weight + poseur quotient - comfort level when walking in cycling shoes x weight weenie rating / resting heart rate. Take that number, and email it to Chris Charmichael and he'll send you a recommendation.

Figure out the most difficult type of terrain you'll be riding. If you can maintain a comfortable cadence up that terrain with a 34/28 (or 29 if you ride Campy) then you don't need a triple.
If you can't you would benefit from a triple.
The answer is completely dependent on your terrain, and your fitness.

So there would be 2 reasons to use a triple: 1)you want a gear lower than 34/34 (which I would have to think would not be many people,
or 2) you want a gear below 34/28, and you don't want to use a wide range cassette and a MTB derailleur.

I'm just saying on my lowest gear, on very steep incline on my 10 speed my speed goes to a crawling 5mph and I can't keep an uptempo cadence. So I probably won't last on MT. Diablo.

Hills? How long and how steep? Unless you are good if not quite good and under 40, go triple.
I have a 53/42/30 Centaur Campy crankset with a 13/29 sprocket. As soon as I go above 7% slope I start using my 30. I surely help.

Well that's the thing. I think it's pretty steep. What is steep for me might be easy for some you guys I guess. I don't really have any measurements that can measure how steep the climb is. I just know that I have to mash pretty dang hard and can't keep a high cadence.

I am a bit heavy though. I'm a little over 6 foot and 190lbs I might add. Not what you would call a pure climber. I don't want to look like Rasmussen though, so that's okay with me.
