Ha, so no silicone but foam, that may be one of the reasons why it feels solid without vibrations.
Did you take pics? I'd would like to see what it looks like, if it was possible.
SD tech is around the graphite handle under the molded grip?
If you've taken butt caps off racquets before, just picture this.
Most racquets have the yellowish polyurethane foam around the outside of graphite hairpin. The inside of the hairpin is usually empty.
The inside of Xi's hairpin is filled with the same yellowish polyurethane foam. So no empty space.
