The best products I think for building your SFI has to be 125 TCredit Pack and Shares of S-Builder.

The 125 TCredit Pack gives you 1500 VP and makes your rank for EA secure while reading and learning so you can do other things to help your team.

By having S-Builder shares I take my workers and include them in my co-op in order to help all of us grow a bigger team.

By using your TCredits in Auctions you can earn the bid and build to earn PSAs to build your team.
