Right and left hand grip system

I am making a lacrosse game, and I need to make a script that handles all the keybinds + animations of the stick. But I need to make it so that you can switch from a right hand grip to a left hand grip as well. I know this is a simple problem but I always struggle with this exact issue because of how messy it can get. So what is the most effective way of playing left hand animations when the player enables left hand grip, and vice versa?
