Hi Abakus

Welcome to TE to another Vancouver girl. That makes five of us now. Lovely that your husband is a Marinoni Man. (I come from Marinoni Land, a.k.a. Quebec, although sadly I don't ride one.)

I suggest that you test-ride both bikes and see how they feel, if you haven't done it yet. It is really what matters the most.

If they really feel the exact same (unlikely), then you're probably having to choose between shops. Pick the bike that is sold by the shop you feel most comfortable with. Or, if you really want bike A but are not happy with the shop selling it, you might want to try another shop. (Ex: Specialized is sold by a few shops in Vancouver; Cervelo not so much though...)

Hope this helps, and looking forward to seeing you around!
