great info thus far guys, keep it coming!

I've heard great things about Rival but I've also heard great things about 6700. I ride microshift right now, one thing I Like is my steady brake levers, I'm not sure I love the idea of ultegra moving the whole lever to shift but at the same time, thousands of others do it no problem, I think I'd get used to it.

I must say, I do like the low maintenance of Titanium yet I like that je ne sais quoi about carbon that just seems like it's going to buzz smoothly down the road.

double vs triple isn't really an issue. At first Ididn't love my compact double but now I actually really like it and I'm on a 9speed platform now and don't have problem with the range so 10 speed will only help me more.
