I can't do full testing right now, as my arms are exhausted from lopping down trees/branches.
However, I've been playing around with TH170, as ControL_ mentioned. I don't have my WF yet, so the combo is MF-H Basalt Aquario TH170MF (Aquario is Hasbro Brand, and used because it is the best CW for this, by far).
TH220 is a silly idea, you'd be better off using a 230 track. It looks about the same, except Lightning can make better contact, so you're gonna get KO'd more often.
HOWEVER, TH195 looks like it carries enough momentum to KO you, and is at a good height to protect itself from being "Upper'd" to heavily. It doesn't seem to be easily Equalised, Basalt still knocks down on LT pretty heavy, sapping it's stamina.
It hurts pretty bad when it collides with LT often causing a HUGE Spin Velocity drop for the Tank, or an outright KO.
LT CAN KO it, don't get me wrong, it's not a 100% counter, but yeah, it looks bloody impressive.
It's an INSANE level of momentum, and it seems to be at an awkward height for LT to do much about. I could be doing something wring with LT, but yeah, this thing is a monster of momentum, and MF at least has enough "cling" to avoid self-KO's. You might try steep banking with LT to get an "up-shot" at it, maybe?
Now, as for why I don't test it if it looks so good: I'd suggest testing only be trusted when done by TWO people. Momentum is extremely important in this case, and as the combo's can't be launched at the same time by one person, you need TWO people.
So, I don't guarantee this for tourney use, try it out in free play
beforehand. That said, DO bring it, and DO try it.
EDIT: Just tried it a bit more at 170. Don't bother, if you don't get KO'd by LT, you'll get outspun. 195 is the prime choice IMO: Lower Centre of Gravity means you're more stable, and much harder to KO, but it's tall enough to grind opponents into the floor, and not fear being Equalised heavily.
EDIT 2: Of course, that's just against MF Lighting L Drago BD145LRF, against other opponents, you'll need to experiment a bit
EDIT 2: Wait, nope, I was saying stick to 220 against MM, but I just realised I accidentally used MF-H MLD CH120XF (with Meteo in Absorb mode to boot), so it wasn't really proper. Still, 220 is probably a better choice regardless (though, if for some reason they use MM on a 145 height against you, you get super-easy KO's with 190).
