if you play on a table or some kind of flat surface, these polyurethane feet will make your stick as solid as a rock. they are 100x better than the TE rubber feet, and probably 1000x better than the HRAP feet. it will feel like your stick is bolted down.
these cost about 2 dollars for a pack of 12 at walmart.
i play on top of my TE box (that is super glued to a table, lol) which has a nice shiny coating so it sticks particularly well.
