You know how when you first start out stringing, you have to look up the pattern for all the Main Skips? And you're probably really anal about it and nervous about getting it wrong and you keep counting and counting and counting to be sure you skip the right ones? And then after a while, you just "know." You don't have to count and in a lot of cases, you probably don't even have to look up the Main skips. You can just tell. You know what I mean? But what about for tie-offs? in some cases, it is kind of obvious that a grommet was used for tie-off before because it is flared. But what about where you have two-piece and there are multiple grommets that look like they could be used? In other words, when you look up a pattern from a manufacturer, and they list the tie offs, what are they basing it on? What makes a tie-off grommet, a tie-off grommet? Is it something about the racquet construction? Is there something magic about 7T that would not have been true of 6T (had they chosen to flare /that/ grommet instead?) Is my question making sense? Basically, I'm trying to determine if there is something special about the positions where manufacturer's specify tie-offs. I wonder this especially in cases where the tie off is on a cross (which I hate). It would be nice, if there were some way to "just know" (assuming you could not use a previously flared grommet as a clue) which holes were for tying off.
