What temperature should I temper D2 slipjoint springs?

I typically use 1125 or so for 154CM springs, but have no idea where to start on the D2.
 
I use 1097 f after austenitizing at 1832 f. I think the normal tempering temperature was too high and the springs I did at the higher temperature was too soft and deformed out of shape too easily.
 
Google of bladeforums threads showed everything from 1100 to 1200. I did them at 1125 with my CM154 springs. Haven't had a chance to RC test them yet.
