I have both the FBM and FFBM, and I prefer the FBM for all around use. It is lighter and faster, and can be used to clear trails without wearing me out. But just for pure chopping against a block, the fatty rules. Of course, a machete beats the FBM for clearing, being lighter and longer. But for all around the FBM is good. It chops well enough and can also be used in machete mode.
