Most suitable and effective isolation platform


I'm looking for the most effective isolation platform for my TW Acustic Raven GT.
Current options that I'm familiar with (but haven't tried out myself):
1) SRA Ohio
2) HRS M3X
3) MinusK BM-6/8
4) Kinetic Systems "Vibraplane" ELpF

Would love to hear your opinions/experiences. Also, if you have other suggested solutions - feel free to chime in!
