I swtiched the stage one blends on ETMX back to Tcrappy, Attached is a screen shot of the opLevs, in units of urad, the green references are from before (stage 1 level 3, 250mHz blends, stage 2 level2 Tcrappy).  The red is now, with Tcrappy on both stages. 

With the 250s, the Pitch rms is 0.7urad with the 250s, with tcrappy it is 0.5urad rms.  (At the same times, the ITM rms is ust under 0.3 urad)
