I'm of two minds about coco and climbing. I liked it when she always rode pancake-flat Tempus Fugit. It was easy for the group to stay together and if people wanted to go off the front, the Reverse Fuego Flat sprint was there to help them.
OTOH, like
msu2001la , I'm gradually chasing the Tron bike (I'm at about 125,000' just now- wish I had known about the challenge a year earlier) and Tempus Fugit won't get me there. Also, I like the challenge of the rolling hills in the sequoia grove. But if you're on the faster side of coco's group, the hills break up the group. And as people have posted here, if you are on the slower side, you get dropped on them.
