I definitely cannot grasp the brakes nearly as fully from the hoods as from the drops. I will brake in the hoods for gentle hills and slopes, but for real security down hills, I like the drops.
I also think the drops are safer for downhills and braking downhill because you can shift your weight back and push into the drops, stabilizing your center of gravity, etc.
Just my .02 ...I really enjoyed reading your post...you are really on the right track and doing great. Now, it is just a matter of time and riding, and you will relax, enjoy, and learn what kinds of things you will want to tweak on your bike as you go.
Beauty of a bike, too!
