I am hoping that the compact gearing of the DA 9000, front (34-50) and an 11 speed cassette of 11-27 will meet my needs.
The riding I do is on the road (50+ miles) with lots of hills and on a paved bike trail.

So, what are your needs? What's the highest high you use, and the lowest low? What gear do you use for flat terrain, and where is it in terms of the rest of the gears? Those are the things you need to determine before you can evaluate any proposed gearing combination.
