Test ride and buy what feels best to you. I'm looking at buying my first new bike in almost 20 years, and I've test ridden some bike I thought I'd love and didn't after actually riding it. Just tried a Pinarello Prince Disk I was sure I'd love and buy...didn't feel at all right to me. I've ridden some bikes that the Internet said I would find irresistible, and ended not caring for. Buying a bike is very personal: get what works for you.
