is also good, basically the same as what I suggested.. my only thought on the way I put mine the way it is, is to make sure fast blade hits first without having to spam it, and then FoF lands in the GCD in between your next move.. although FoF won't be on the first fast blade, it's relatively weak attack anyway, so not missing out on much as far as that's concerned.. either way, they'll both work, just use what works best for you
