Thanks for the input, Rath! I love your rotations!
Indeed, using Ingen2+Rapid syn can substitute the use of PBP and some CS IIs, which saves steps for more Hasties. But what Immut was referring earlier, was doing Ingen2+Rapid Syn WITHOUT utilizing MaMa nor MuMe. Thus, I don't think simply using Ingen2+Rapid Syn would save any steps when MaMa or MuMe are not being utilized.
