I just purchased a Seven Axiom. I'm 5'3" with long legs and a history of wrist problems (carpal tunnel - yuck). Seven worked with my LBS to come up with a bike that does not bug my wrists, rides like silk, yet is lively and responsive. I adore it. :)
Seven was fabulous about communicating with me through the frame production cycle. It was great to be able to email or call with questions from serious to trivial ("Hi, can I change my decal color choice?") and be taken seriously.
The only other titanium bike I've tried though is the Wylder "Queen of the Road" (also a very nice bike). I wish I could give you some input on the Odonata - best I can do is to share my experience with the company.
