However, I agree there could be merit in re-investigation to establish whether the proposed benefits are in fact realistic and also to identify all the pros and cons.
Fodd bynnag, rwy’n cytuno bod gwerth posibl edrych eto i weld a yw’r manteision arfaethedig yn realistig mewn difrif a hefyd i nodi’r manteision a’r anfanteision i gyd.
