Since then I have bought like 5 sets of grommets, apd and pdgt.
I found that any Aeropro drive's grommet fits any aeropro drive in cortex/gt/lite/even jr versions. Not sure about original as I have not tried. PD and APD's grommets do not fit each other.
Rackets feel very cool and shiny everytime I put on a new set of gromment, bumper guard. Bab gromments and bumper guards are on the cheap side or something cuz they break easily. I never drop my frames though.
