Timbernation, I do like their racks, very solid I have one. Spikes, well I used spikes under my book shelf stands, which are filled with shot, holding 40 lbs Vapor Breeze speakers, ( heavy) siting on a 1/'2 thick wool rug. Well it worked great, until we rearranged the room and found that the spikes had put small holes in our tile. The wife was pissed. So I went to Herbies Cone/Spike Decoupling Glider and I really like the outcome and it saved our floor.
