The regular C7 is the same, it looks like you'd have to replace all the grommets using the strip individually which sucks. Even if you could find a replacements strip (which I can't find) it would have to have the non-spread grommets with the ends not spread out wide for cleaner stringing.
About to string my own C7 which I hope that I don't have to re-string too often! Or you could just buy a new C7 if you have to replace the grommet strip and sell the old one
Just from initial inspection it looks like generic individual grommets would be a suitable replacement, since the frame underneath the strip appears to be the same as the sides where there are normal individual grommets. But of course you'd want to avoid replacing the strip for as long as possible
I don't believe the strip will need to be replaced to be honest. The material seems pretty tough (not as tough as Yonex shared grommets) but seems tough enough to sustain multiple stringing. The only thing I would watch out for is the last grommets on the ends which may get damaged over time from stringing. Those may need to be cut off and replaced with regular grommets.
