It dosent work like that manI'm sure some networks offer more than AdSense 68% rev share.
Google will always take their cut no matter you are in network or not
Thats why you have in analytics Gross Revenue that the total money channel made,from that Google takes their cut,then after Google takes their cut,you then get Estimated Earnings which is after Google Cut.If you are with Adsense everything that is in Estimeted Earnings Will go to you.But if you are in Network,Network will take cut from Estimated Earnings leaving you with less money. Samo dobro nameran savet,vidim da se ne razumes mnogo u ove stvari
Peace
