I want to put a y in to plumb a sink and seperate waste disposal. Since I obviously don’t want to blow back up the sink with the disposal, do I need to stay with 45 degrees or could I use a long bend 90? Geometry limitations noted.

I can't quite picture just what you are trying to do.
That said, I don't see why sanitary tee , which has the sweep won't work.

A GD does not pressurize the line. Simple gravity feed.
For a two bowl sink A simple T is used to connect one side (which might have a GD or not into the tail piece of the 2nd side. Then the tail piece feeds a common trap.
Now mine have two separate traps that feed in to a Y and then the sani-t in the wall.
I don't believe that it mets current code, but it works with any problems.
But the trap arm from the Y to the sani-t is only a couple of inches.
I can see more problems if the trap arm was at maximum lenght and water flow in one leg to symphon water out of the other trap.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
I have a small/large sink combo. The big bowl is 10" deep and the little bowl has the waste disposer. After studying the geometry, the waste disposer line can't go straight to the other sink unless I go down instead then 90 degree turn and over. That is one extra bend.
The other choice is two p traps like you noted, each before the Y fitting. Had no idea a 10" sink would be such a pain.http://www.etherhuffer.typepad.com
" 86618.4 in reply to 86618.3 I have a small/large sink combo. The big bowl is 10" deep and the little bowl has the waste disposer. "That is the same setup that I have. And I had to run down and check it.You are right. If the line ran straight from the GD it would hit the big bowl right at the strainer basket.But I don't see any problem with puting some 90's and dropping the line. Other than it takes up a little more undercabinet space.I don't see a clogging issue. Not if it has to pass through the trap it can handle a couple of 90's.

Thanks, and you are right. Our sliding shelf under the sink won't do much with all this plumbing in the way. Time to go get lots of elbows and traps. Heh.http://www.etherhuffer.typepad.com
