Cyclesome - I have similar measurements to you and I ride a Pilot 2.1 WSD. I've had mine since April and I love it! It has a very smooth ride. After my crash, the owner of the store test rode it (after repairs) and commented on how smooth it was! Test everything you can - sizes and makes and models. They thought I would be better on a 51 to start, but I felt crunched. You'll know when you find the right one - you'll know.
