If your insisting on being pedantic about this, then I could have used examples of the difference between Tarmac and carpet.
I figured it would be easier for the masses the understand why the difference in bottom deck if I said foam and rubber becuase it's obvious that you wouldn't use the same for both.... Jeez
obviously they're on rubber but Yokemad is trying to stir things, just like in the yokomo BD5 thread....
Anyway, back onto something productive on this topic......
