My experience with the Oreas was to use ones that would use up about 40-60% of weight allowance. The ones that used around 90% didn't have anywhere near the same results.
Also, despite what Isoacoustics and Music Direct told me, using them under the feet of the component gave me the best results. They recommend placing them directly in contact with the bottom of the chassis and that was a really torturous affair.
Moving them just a fraction of an inch this way or that, elicited large differences in where they accented or attenuated and never gave an across the board result that was satisfying. There was always a trade off.
Hope that helps,
