Over 20% is really really tough. However, long sustained climbs from anywhere in the 6-12% range is doable. I'm thinking of taking my old frame and putting a 50/34 on it (using my same cassette) to get just one more gear for riding the mountains.
My compact is perfect for my usual terrain and racing. I run out of gears on the top end more often than on the low end. If I lived in the mountains, I might prefer a triple, but I think even then I'd be more inclined to just put more gears on the back--like maybe a 50/34 with a SRAM or DA7900 cassette with a 28 cog. It's not that much of a difference in gear inches, but my current gearing is *almost* enough for steep grades.
