Double lav with drain 10' from first lav

[chuckd83]

Not a professional plumber so I'd like advice to make sure what I'm doing makes sense, especially the wye and 90 deg bends for all the horizontals. I have a 2" cast iron hub I'm attaching to using a fernco donut.

I'm remodeling my bathroom which entails going from 1 sink to 2, and moving the sinks. See attached plan. Old on the left, new on the right.

My plumbing plan is also attached. Let me know if this makes sense. Thanks.

Can I use sanitary tees on their back (and stomach) for the venting?

I'm going to go ahead with my plan and use sanitary tees since nobody seems to be responding.

Page 5 item D of the second one seems to say that the santee on its back is OK for a pure vent.
