It really depends how much of our time open up. Given AM5 is the cap for yellow we have much less time than hoped, and there is also a danger that TRF5 is the cap, too. In that case both TRF and AM would be significantly harder to max than FVM/SCS before breakthrough. While as far as we know it's not because it is significantly higher quality than FVM/SCS, I think it might be a combination of "Ling Qi is actually really damn talented at what FVM gives and there is an implicit bonus there not told" and "FVM/SCS purposefully begin so low level so that it's easier to learn thorough".
Basically if we don't need to trade AM
and we have time I would be all for a wind/thunder leg/lung movement art. Our speed is actually stagnating lately and I've been thinking we need more of that. However, Yan Renshu art is probably higher priority than that to me, and maybe even the art in the shaman bag if it turns out to be the Shaman's musical art.
AM5 being a thing before yellow and probably needing 150? successes change things, and while it also mean it will be
really damn good at that level, it also means we can spare less time learning new arts.
@yrsillar considering the bookkeeping error for AM3 meridian, are you sure TRF3 doesn't need a third meridian?
