Great call on the Rubicon LJ.
Don't let the OPDA issue scare you. If yours does have it it's not that hard of a fix. Funny thing is that I don't personally know of anyone that has had the issue and that's between about 10 TJs, including my LJ Rubi. I know it happens but feel it has been blown out of proportion. Check it out just to be sure.
