final update on this affair.
i have made contact with pro kennex staff in taiwan, and they have setn me the right grommet set for the redondo.
These are a PERFECT fit, and in fact also fit the black ace 93
turns out TWE europe send the grommets for the 98 version... no wonder they did'nt fit...
and now i have to buy a 98 just because i dont want to waste a brand new grommet set.... :P
