I thought you didn't like internet gurus lol, jk, seriously order them up and take them to a few local speed shops and get some opinions. There are a few performance shops that will give you an honest unbiased opinion and deal with nitrous. Best case is you discovered a great deal to be passed on to others and worst case you send them back. I'm guessing most guys have never even laid eyes on them as they just buy a kit or used name brand plates so really you won't know until you have them in you're hands.
