Will Shock Mats/Tiles work for building a small, semi-mobile sprung floor (for Irish Dance and Belly Dance) to meet the following criteria: 1) Protect joints from repetitive, high impact 2) Dance rhythm from fiberglass taps on shoes can be crisp but dampened upon impact 3) Anti-slip but not so strongly that the floor will "grab and trip you" 4) Withstand impact of a fairly sharp sword blade. If not, could a piece of wood be safely affixed to the top of the mat/tiles? Thank you.
