Definitely is much better to pursue PSA's because you will have DC and matching points from them and,as You know, they will get their own PSA's.So, you will make team.Team build is very important for further success in business,duplication through team ,DC's, and matching points from every one from your genealogy who is EA2 or higher rank.You just have to be Team Leader to collect all benefits and you will be awarded with CSA's anyway from SFI.
Hope this will be helpful.Good luck!
