any RIR-->PERM approvals??

Dear gurus:

Have you guys heard any RIR-->PERM conversion cases actually being approved? I have RIR pending from Sep2004 and just finished all the PERM recruitment efforts (identical). I can’t decide whether to send in the PERM application and transfer the RIR PD. I personally don't know any successful stories. I am just wondering whether any of you guys know people who have done it and actually had their LCs certified. Comments and suggestions are greatly appreciated. Thanks a lot.
