I just buy a new CS when mine wear to the point of aggression, they aren't expensive due to cheap pre-checked RBV6's flooding ebay. As for manipulating the launch, I generally prefer my Basalt BD145 to stay still, which is much easier with a good CS (and as I said, I keep/kept spares for competition), so I have little use for manipulating launches. It's not a combo I rely on, either, so I generally don't have to KO too often (and when I do, I can launch a calm CS violently enough to get a decent shot at KOing the opponent, and have pulled this off to recover from 2-0 down in a tourney).
As for MB, I simply find it much easier to KO with most combo's, though, for example, I found Hell Kerbecs BD145(Normal) R2F did worse against MB due to the fresh R2F meaning the only real contact made occurred between the BD145's. I just find CS more consistent against more common opponents.
Anyway, just to make things clear, I asked for tests of Basalt BD145CS and This Combo against that Phantom AD145RF combo (not that I doubt it's abilities, I have one coming so I'm very interested), and you basically said you'd done them in another thread, which only contains tests of it vs Basalt BD145MB. That is my main issue, not your personal preference of tips
As for tips helping KO's, movement is a huge factor, but I do understand what you mean. Though, Variares on S just reeks of self-KO to me, ahah

And, TBH, put on RF, almost anything can KO, say, the old Burn 145WD stamina beys.
