There isn't a Loesch grip, they are all custom, and you can specify whatever you want. If you don't know what you want they will help you.

Low is pretty popular these days, it goes with a bent elbow style bow arm, which is good for follow through with the low holding weights of the compound. The low wrist also helps get a torque free grip, it is not the only way, but it is probably the best, that allows fullest contact. On the negative, it isn't the way most people learn to shoot a bow, and it can cause some complications as to draw length etc... When you get a new grip, there really aren't any guarantees on draw length anyway.

I imagine the Shrewd medium would be low enough for most people.
