Another Orbea fan waving hands. I have the purple 05 Dama Race and I love it too. I'm only 5'0 tall and have the 49. Its the best fitting bike I've ever ridden. I have mine set up with Ultegra 10speed and a triple. My knees demand that little granny to get me up the hills around here.
I say try one and go with what you love. You can always sell your other bike.
