Hey, maybe it's just me -- or, more likely, the exceptionally spongy nature of my floor "hardwood" floor -- but I've had my Thiel 2.3's on spikes, and the spikes on pennies, for about three years. So far, the spikes have literally drilled through about 8 pennies (I replace them from time to time). I'm seriously considering a major upgrade . . . to nickles. Figure it will cost me about 30 cents for a full set of six. I think it might be worth it.
