I'm fan of waste not for 1 and 2 star items. My rotation is normally:

1. Inner Quiet
2. Steady Hands 2
3. Waste Not 2
4. Hasty Touch x 4
5. Careful Synthesis x 3/4 (1 away from finish)

I don't waste any of the waste not in my rotation. The only time I ever try to use great strides is near the end of a synthesis when I go to hit the lvl 50 carpenter quality boost skill.
