In the development of Launchtec blades I have tried different strengths of blades to cover 8,10,12 thousands of an inch steel blades and found it made no difference.
My conclusions, rightly or wrongly is that changing to a stiffer steel blade only seems to slightly cut down the vibration, but it will still come further past the resting point than a Launchtec blade.
