Recommened ROM

I haven't seen any devices actually fail due to over-flashing at this point.
Chefs would certainly experience this more than average.
One thing I have found is that if you don't clear your memory by flashing back to stock ROM or using Task 29 (posted here) your memory retains portions of the previous flash, even with a hard reset.
I've flashed about 20 to 30 times w/o issue, but do a Task 29 between each flash.
