I'm a fan of the Orbea Diva as well! I'd love to have the BLUE one!
Though...it'd still be tough to decide which of the two I'd have to ride. LOL
Don't leave out the Giant OCR-C W from your consideration! I too am 5'6-7" and my bike fits me perfectly.
(I recently found that it takes off-roading quite well too! - right Wahine?) hee hee
edit:
I also love Shebeest clothing... great styles! LOVE LOVE the blue leopard jersey print!!
