Eastern/Semi-Western forehand firmness?

[TalkingTennis91]

On the Eastern/Semi-Western hybrid forehand (a la Federer), what should the firmness of the grip, wrist, and forearm be like?

Thanks!

groundstrokes should have a firm wrist but not as firm as volleys

as loose as possible while under control, ie: not floppy but very relaxed.
