• selecting a first head from a plurality of heads, each head including a mount with a post extending therefrom, the post including an area of external threads, wherein said heads comprise a plurality of different geometric shape cross-sections, at least one head having a geometric cross-section different than the geometric shape of the corresponding cross-section defined by the base and sidewalls of the recess of at least one band;
• and
• rotatably interconnecting the external threads of the first head with the internal threads of the first shank to releasably secure the first head to the first shank with at least a portion of the mount positioned within the recess of the band;
