Thanks for the explanation, Fletch. looking at the pics, I'm assuming from a practical standpoint
the only difference would be that looking at the back of an arrow on the string with typical cock feather out (RH shooter) the back of that feather might be at exactly at 9:00 o'clock, 8:30, or 9:30 depending on the indexer used. Don't think I'll loose any sleep over this one. I'm always amazed at the slow-mo video of archers paradox and how much the tail end of the arrow clears everything by! My sealskin rest has been on for years and still looks new. The only reason I asked is that I will eventually see a little wear on the tips of the "5 o'clock" fletch after a cajillion shots. If the LH indexer would help that, I might spring for one.
