I use Hammer products exclusively, but I must admit that it can be confusing since they have so many products and supplements.
Use Heed when you would Accelerde. Use the Hammer Bars for the Cliff Bars. Use Recoverite for the Endurox R4.

What I've listed above is basically what I use with the addition of Endurolytes and Race Caps.

For longer rides 3+ hours with lower intensity you can swap out Heed for Perpetuem or Sustained.
