I'm late to this thread, not sure if this will be helpful, Karen, but here's my experiences with leaning. I bought a Trek Pilot this summer after four or so years on a Trek 7100 hybrid. I was hesitant about making the switch as I was worried about placing too much weight on my hands and about getting used to the riding position. Four months later, I would never switch back to an upright riding position. I am so much more comfortable on my Pilot; I like stretching out to ride, and the different hand positions keep my hands so much more comfortable. We went on vacation recently and I took the hybrid instead of the Pilot because I knew we'd ride on paths & fire roads. I didn't ride much at all because I was so uncomfortable on the hybrid.
Enjoy your new ride!
