Double, Compact, or Triple?

I would create a poll but I'm not sure how to.

I'm curious to see what most people are using.

My Lemond I've been riding for the past two years has a triple. I just bought a new bike off eBay (w/o really thinking about gears - I was after the frame) and it has a Double with 12-25 in the back. I'm really missing the granny! After searching through old threads, I'm guessing my best bet is to swap out for a 13-29 in the back (all Campy Centaur parts). My last ride on it with some hills left my knees hurting...

Guy at the bike shop said you could swap out individual rings on the Campy cassettes, but from some web searching it doesn't look like you can on the Centaur, unless you are getting 2010 parts.

I have a triple. I've never tried a double or compact double, so I can't advise. But I do know that I need that small chain ring.

I have a bike with a triple, a bike with a really small compact double 46 - 33 with an 11 - 34 in the back and a bike with a standard compact 50 - 34 and an 11 - 25 in the back.

I think of myself as a pretty strong rider, not super fast, but strong.

Yesterday we rode 46 miles with a big climb coming at mile 33 ish. The climb was 4.5 miles with an average grade of about 7.5% - sea level to 1600 feet. I cannot believe how much it hurt to climb those 4 and a half miles in my 34 - 25. No knee issues just some burning muscles and by the time I got to the summit I was seriously fried and it was NOT all downhill to the car. I'm thinking I need to see if I can put a 27 on it. It's also the first ride I've ever wanted bigger gears as I spun out in the 50 - 11 on a downhill. But do I really need to do more than 38 mph?

Yeah, if you're having knee issues... probably want to swap it out for something easier.

I have SRAM compact doubles on both 'good' bikes - with a 27 on the roadie and XX 36 on the new touring bike. I just think doubles are lighter and less hassle, and unfortunately I needed this one before Apex comes out. The tourer has mtb wheels (and will take 650s) so the rear wheel becomes a good mtb wheel as well, and should tackle anything. I hope,

The tourer had its first real ride Saturday - to the snow up Mt Donna Buang, which is a 20km climb with some mud. No knee issues, which is important to me after a knee injury.

I have a traditional 52-42 on another bike with a 28 on the back but it's not as versatile. I'm more endurance than speed though, so ymmv.
