There may be a misunderstanding about what LFB is doing. It's simply a type of gamma function that maps an input value to an output value: You can't lose any details and you can't boost only certain things. It is a 1 dimensional input giving a 1 dimensional output. It's doing exactly what I would expect feeling wise. LFB isn't aimed at DD users although a little can still help. It's aimed at wheels that don't have a good response to light forces so need the boost when there isn't much going on. For those of us lucky enough to have a DD wheel, we just need to up the FX slider if we want more of those effects. I personally like the control of being able to split the LFB but it's only a preference.
