That should be what the latest version I sent you does. Are you sure you uploaded it?
I updated the first rule to be:
Shipping & Handling : Trigger = SubTotal of StandardQty > 0 AND SubTotal of EliteCaseQty = 0 AND SubTotal of PistolCaseQuantity = 0 : Calculation = Flat rate $9.50
Which should make it so that the $9.50 base charge for a Standard item wouldn't be added if an Elite or Pistol category item was in the cart.
