If your learning the game don't bother with a HUD, focus on your hand, chip stacks, bet sizes, action etc...
Once you've play a shit load of hands and you understand position, pot sizing then you should add a HUD.
Also you should only be 1 tabling while learning, paying attention to all the hands, not just the ones your in. If you do Multi-table a HUD is essential as you wont have any reads and can play based on the stats you have.
