I haven't personally weighed the ig grommets but the ig grommets are clear while the mg/yt are black. I think the weight difference should be imperceptible.
I think the weight differences are minimal, but I have heard that the IG Prestige grommets were PITA to string. Maybe the softer material grabs on to the strings, but it may be something to consider if you string your rackets.
