So I've been looking around and everyone I have read posts by says any COP other than OEM is a waste of time.

Do I need the OEM ones from the stealership or are the Ford Racing COPS just as good?

I'm changing them because I have a hesitation under light load and when decelerating. I've replaced the fuel filter, plugs and cleaned the MAF.

If you think it's something other than COPs feel free to send your .02 but please ALSO answer my Original question.

Thanks in advance all.

I've never heard that about COPs...you'd be much better off diagnosing the problem then playing "miss and hit"...you could have a clogged injector, it would be best to put the car on a dyno or scope and see what is going on...

when a COP is bad its pretty noticeable (may throw a code)

I would not just change all 8?

I would go back stock I used aftermarket COP's

and they failed after a few years put the stock ones back in.
