I'm going to give the Sagma a try. I'm not concerned about stand over but with the 76 degree STAs on my current bikes, the nose of my WTB Volt/Specialized Phenom is in the way when I ride out of the saddle without dropping it. It'll be nice to switch between standing and sitting without being poked like I did for so many years on bikes with 73-74 degree STAs.
The suspension/rail technology seems pretty interesting as well.
Off for me as well. The wrist measurement gives me 127mm but the memory foam at my LBS gave 150mm. I've got a WTB Volt 150mm and a Specialized Phenom 155mm on my current bikes and both are comfortable.
