Amongst those ECA products that will give you a good royalty, and the TC direct products that will give you the best VP, DC, etc., you want to promote the products that your downline and referred ECAs have to sell. By helping them sell their wares, they will become stronger financially, and more positive about the ECA program. Thus your whole team will become stronger. And you will gain matching VP if you have BTL or above and your ECAs have their EA2.
