As per my knowledge I would suggest you to pursue PSAs, you will make team.Team build is very important for further success in business. You just have to be Team Leader to collect all benefits and you will be awarded with CSA's anyway from SFI. But, I believe that both PSA’s and CSA’s are important when you are building a business. So concentrate on getting your PSA your CSA will come in time and you may want to bid on them to maintain your TL position.
