Never used PbP as part of my 3 star rotation, i always relied on RS to free up all that cp for an additional MM II.
But if you are all about minimizing the risk of a fail, then i would suggest SH II > PbP > RS and you can finish with 3x CS II.
My personal rotation is SH II > 2x RS > 3x CS II
You don't rely on ING II and you free up 30 CP from your progress steps that can go towards anything else.
