Tri bike for a shorty - Felt or Orbea?

I am looking to purchase my first tri bike, and am curious about other people's opinions on what seems to fit best for short women.  I am only 5'3", and neither my legs nor my body are particularly long (I am long waisted, which doesn't help on the bike at all).  I would probably say that compared to other people my height I have a short reach and average-length legs.  I have been looking at Felt (probably the B2), but am considering an Orbea (maybe the Ora, perhaps but unlikely the Ordu), and have also been considering Quintana Roo (the Caliente).  I want a bike that I can grow into so that I won't be looking to upgrade again in 2 years, and also one that fits really well and is very comfortable.  But I am still new to biking and don't want something that will be too much bike for me either.  I am leaning toward the Felt, but I like the bike shop that sells the Orbeas better, and I'm being swayed in that direction because of that.  I have ridden a B12 briefly and an aluminum QR, but won't be able to ride the Orbeas.  Any thoughts?
