I tend to have a 40 degree torso angle on my bike with moustache bars, no problem on the girly-bits on the Brooks B67 on that bike.
My bike with drop bars, I spend half my time in the drops, no problem on that Brooks B67, either. (bars at same height as saddle) Dunno what my torso angle is on that one, certainly less than 40 degrees.
But then, I can also sit on a wooden chair in my undies with my elbows on my knees and not feel any girly-bit squooshing (the test for needing a cut-out). (or, if your saddle isn't wide enough or has too much padding, it's the comparison test for you needing a different saddle!)
If you know you need a cut-out, you might want to wait for the B-17 Imperial. (Brooks with cut-out, and no grumpy company owner like with An-Atomica) If you have wide sits and need a cut-out, hang tight for the B-68 Imperial. Check with Bill at Wallingford for release dates.
