So I didn't ask for advice on this because I wanted to try it anyway, but basically I slightly drilled out the string holes in my sv ps85 in order to make the newer (and the only affordable) replacement grommets fit, and it worked! I also had to chop up the grommets to make them fit.
Before anyone goes nuts, the affordable replacement grommets just would not fit, and I am not about to be sanding and shaving them. I was also not about to spend more on grommets than I did on the racquet. I want to actually use this frame as a piece of sports equipment. It was not in showpiece condition before I got started. And yes, I enlarged every single hole, even though many didn't strictly need it, for science!
I did it to the max, and used the throat grommet replacements instead of leaving the originals there, which were fine and could have been used again. The throat grommets weren't even the best fit sliced apart. Before stringing there was daylight between the grommet and the frame because the 2-grommet pieces were a tad too narrow.
With the proper grommet slicing and gentle drilling, the other grommets fit nicely.
My drilling tips would be to juuuuuust sliiiightly enlarge the holes. I test fit drill bits until i found one that would actually go through snugly, and used it as a kind of rotating file inside the hole.
This worked great. I didn't want to report on it until I could try it out. They just put the nets back up at my local court and I hit about 50 serves with it. nothing but sweet and accurate when i hit them right and no unusual vibration off-center.
As you can see in the pics, the grommet hack job is intentionally sloppy, just because i was curious. I even did it asymmetrically, making one less cut on one side. there's a little bulge there. but from two feet away, she looks sweet!
