I hereby confess that I switch grips depending on what I am trying to do.
generally, the deeper in the court I am (or the higher the incoming ball), the further around I take my grip (towards W)
I don't know if I would recommend this to anyone, as I have been playing 35 years and can hit a FH with pretty much any grip, it's probably better to find a grip that works and stick to it.
to OP, if I were you, I wouldn't make the switch.
