Sure the extra cleave from RB(meatcleaver) is nice and all but taking into account that your weapons are alot better as SMF and that you will see quite a few executes throughout the fight then SMF will be alot better.
I haven't checked to see what other TG-warriors are doing on that fight, but me as SMF does 221k dps (10manHC).
Using meatcleaver as much as possible but no WW inside CS-windows
Note that a Fury TG should use WW inside CS-windows (instead of WS, I mean, obv not instead of RB), hence having more RB with 1 stack of Meat Cleaver.
If your weapons were of same ilvl, I'm not sure SMF is better than TG.
But yeah, as Zcorn said, your 1-hand weapons are far better, so go SMF.
