a lot of times rec players using 1hbh extend their wrist on contact as the result of locking the wrist from the prep. This opens up the racquet face at the contact. If you hold your racquet in normal E bh grip and address the contact point and make sure your wrist is not extended but either neutral or slightly flexed, then the racquet face will be closed. Once you put this angle in your muscle memory and practice you'll be able to hit as hard as you want and balls won't fly. And you'll find the neutral wrist can be much more firmer than the extended wrist.
Changing the grip toward more extreme due to racquet face angle instead of adjusting the correct wrist usage is not the best solution and will cause other problems down the road like dealing with low balls. Learning how to correctly use the wrist angle is a much better way.
