How many incentie networks should I apply to?

I’ve just started my own GPT site and want to add ad many offers as possible. The problem with signing up to all the CPA incentive networks is that they pretty much broker offers from other networks and you don’t know who is broking of who.
So I’m here to ask, what is the best incentive CPA network/s to sign up to, to add offers to my site without adding duplicate offers?
Thanks
