Spinach is delicious, hands down. It just needs better marketing - especially for kids. I also ordered a mixed set of Yonex grommets and they seem to be indeed sturdier than the ones I got from Aliexpress. But since I am mostly a low-to-mid-tension stinger I am saving those for the right opportunities (well... for my own rackets...). Do you also cut the shared grommets close or even flush to the frame on the inside? Sounds logical to avoid that they are split, but I've never seen that done on an actual racket.
I cut the mbs and normal ones close to the frame and let ~1mm space between my Knipex and the frame. The T grommets (from the Armortecs) are shorter. Mostly they don't need a be trimmed.
