If this were hell bd145 (normal) r2f, mb would be a great option, as it basically limits contact to bd145 on bd145, whereas cs doesn't do this. Howecer, in this and most cases, my preference for cs stands.
Yes, 10% is a bit low, but then, the 90% gibsonmac got is also unrealistic, though probably more of an example of why we require 20 rounds instead of a meagre 10 than anything (please be mindful of this in future).
What I'd like to see is some attack v attack testing, against, say, mf variares ch120rf or whatever, to see if it holds any real advantages over that combo. Heck, I'm not entirely sure what that variares combo struggles against, but if there is a combo that gives it trouble, testing this conbo against that would be nice. To see if there is any particular area where variares doesn't outperform it (though, there is, always room for a "second line" of combo's, for those who lack the "very best" parts, which I guess we do seem to forget."
By the way, meow, I do recall quite clearly people being told to ONLY include the combo in the thread title, and nothing else. It would probably be advisable to remove the "hell strikes back". Just include that full title in.the actual body of the OP, if you wish to keep it (I would, it's a nice title).
