I'm pretty much a newbie, too, but have already learned a lot from reading the different threads here. I do know that you should try out different bikes if you can. The Dolce may be your bike, but don't be afraid to try out other models and brands if you can find dealers in your area that carry your size. I thought I wanted a Ruby, but it ended up feeling all wrong.
Have fun and enjoy! I've only been riding a couple months, and am having a ball.
