What to do after SLS/SE1 is mastered?

I have mastered the entirety of SLS and all of the PE's and iM's. Should I continue to do SLS/SE1 as the SLS days are scheduled until Foundation 2 comes out, or are there other things I can and/or should work on?

I too have mastered SLS/SE1 and have been doing it for the mean time until F2 comes out. I have also been doing SLS in my spare time. I can do 10reps on each leg. I would recommend continuing on until F2. You can attempt SLS in your spare time if you want.
