Which network for more conversions

I just started with CPA and to test some things out I started with a couple accounts doing the 'Free Iphone' method/niche with OGads.

So I got some conversions and they are very profitable because the payout is 8 dollars per conversion. But I noticed all my conversions are from an actual 'win a free iphone' PIN Submit offer in the OGads content locker. This made me think it would be much more logical to promote an offer like that directly. Because I'm sure a lot of traffic clicked on my link 'to win a free Iphone', then reaches the content locker which in some cases shows app installs and other deals and people click away. So do you think I should move to another network to be able to promote offers directly or maybe remove all other offers in the content locker so everyone only gets to see one 'win a free iphone' offer?
