lmao Well its all Bluezee's doing. He has about as much skill with XF (controlling it, as some members find it hard to do) as I do and at one of the tournaments, just as you explained, a bunch of people talked it down while he was talking to them. He then began to completely smash all combinations brought to him, from Canada with love.
Once you get used to the whole experience XF gives you, these results in the OP are achievable, and by no means hard to get at that point. I think if you read the OP over, I mentioned it. I understand your doubt in this combination, as I would have said the same too. I will be attending a lot of tournaments held over the summer and I will personally show you what this is capable of. I actually need to practice with it more since I've gone back to using RF, which essentially mutilated my sensitivity 'setting' gained by using XF.
There is a combination of reasons why you don't see MF Meteo LDrago CH120XF at your tournaments;
1. Who the heck has XF? It is not a common piece which hinders this entire combination from growing.
2. Those who do have it don't bother 'practicing' their shooting techniques with it since they didn't get such amazing results fast, like the OP.
3. They have XF but don't use it. (You'd be in that category, and I'd love it if you came out of it and practiced with XF.)
Practice a lot with it. Thats all I can really say because I have so much information on this customizations launching tips I can't even begin to organize it onto a single post, so if you stumble onto a combination (like Hell BD145WD) which you cannot either smog out with Tornado Stalling, or KO it (That usually comes almost at a constant when your good, and can control XF your own way.) PM me and I'll either imagine the scenario and place a launch and track height for best results with MF Meteo LDrago CH120XF or I'll plain test it [MLD vs. combination X which troubles you] myself and tell you what [launch style] worked best for me.
Is this coherent enough? I have so many thoughts about this going through my head, man.
Anyway, see you in summer and you'll see this combination. Seriously, practice with it and you'll get what I mean.
