Not too clued up on X-metals so i'll appoligize if this has been cover or is incorrect. Thought this might help out one or two on here. I've just been given info about Linegear doing rubbers for the Romeo's, Mar's & Juliet's. I don't know what the quality or fit is like but thought it might be of some help. CUSTOM RUBBER - Complete rubber set for ROMEO1 - Oakley Custom Replacement Lens shop [LINEGEAR] Oakley Custom Replacement Lens shop [LINEGEAR] Mods sorry if I shouldn't be posting the link but it is not an auction it is direct from their site, if I shouldn't have posted tell me & i'll remove it.
