1. Hybrid Twist

2. Strategy To improve hybrid twist we select two batches –First for immediate use require no modifications. Spread of widths well within geometric tolerance (~60%) –Second are higher twist and are first heat treated to reduce the twist and then mounted to account for the residual twist.

3. Heat treat Batch 1 – non treated Yield ~60% Mean twist = -30 m rms = 130 m Batch 2 – heat treat Remaining will be heat treated and expect* those to have mean ~ 400 m and rms ~ 50 m based on limited stats. These will be mounted separately. * Based on limited statistics of heat treating. High twist hybrids move to approx 500 micron twist.
