Grommets are already placed for starting and ending knots on most all rackets. Am sure they’re placed there for a reason.. to minimize load in any one area wrt to knots? I never questioned this.. so would like to know.
My pet peeve is YY which skips two holes at the throat for ending of crosses. thats just untensioned string.
I add extra lbs to compensate, but sometimes im riding on the edge for Eg string 28lbs on a racket rated for 28lbs.., last pull is 30 lbs to compensate for the untensioned string.
But not all brands do that skip 2 to end.
Btw, 3 strings through 1 shared grommet, that must have taken a bit of effort.
