Sage Wood blocks vs Herbies feet for VPI Nomad?

I have a VPI Nomad with ortofon red cartridge with a pair of Grado RS2i headphones. Eventually I would like to get a Grado reference platinum 1. Turntable is on top of chest level book cabinet. I know not the best area for sonics, its there because of big dog and small children. I was originally going to get Herbies audio labs tender feet, soft version with a 2mm herbies mat. I then saw these interesting wood isolation platforms, feet set of four advertised here on audiogon, Safe Wood, I think that is right. If these blocks are better, should I put then next to rubber feet but not under them, just directly under turntable plinth? Also, Herbies mat good or does it kill the sound, more damage than good, other mat or no mat at all? Need expert advice. Bang for your buck here for my modest system. Gerald.
