Fit issues for long legs/short torsos
I'm sure this is a common problem, so I'm interested in what solutions have worked for others. I am a little over 5'5" with an 81 cm inseam and long femurs. Short torso, short arms, narrow shoulders. Basically, I'm proportioned like a T-Rex.
The online fit calculators suggest a 48-49 cm top tube. Local bike store suggests a 51 cm top tube. On a frame that small, I need the seat quite high, which makes for a big drop between saddle and bars, which means wrist and neck pain on long rides (for me, anyway).
I've been riding a 42 cm cross check (52 cm top tube) with the seat set way back, a short stem, and an uncut steering tube. Looks a bit funny, but it gives me an appropriate reach and puts the bars just slightly above saddle height. I'd love to get a lighter bike for weekend group rides, and have looked at the Ruby, Synapse Carbon, Scott CR1, Orbea Onix, etc. For all of them, even with the taller head tube, my bars are pretty low compared to saddle height when I ride a small enough frame to get a 50-52 cm top tube.
Are there any other frames out there I should look at that are particularly good for more extreme WSD body types? How have other folks solved this problem?
I am guessing a bike fit is in my future. In the meantime, I thought some of you might have some ideas for me too.
Thanks!

Oh thanks! I'll add them to the list.

Thanks so much for the helpful advice! I've been reading lots of geometry charts, and it finally just clicked for me how the seat and head tube angles, top tube length, and stack height all work together to affect reach. Eureka! No wonder a 51 cm top tube can seem long to me- I have to scoot my seat way back to get the proper setback for my femurs, which effectively lengthens my reach. And on a small frame, the drop to the bars puts me in an aggressive position on what, for other people, would be a more upright bike. Darn these short arms! :)
I've got a chart going that plots reach and head tube height for each of the bikes I mentioned in my original post. In my size range, the Giant Avail Advanced came in with the shortest reach/highest head tube combo, with the Ruby and Synapse in a tie for second place. I'll research each of the brands mentioned above now and add them to the chart. This stuff is so interesting!
I've also spoken with several fitters, and I've narrowed the field down to a couple who seem particularly promising.
Thanks so much for the suggestions!
