The Optimus is for "down country", not a typical XC tread but designed for speed, climbing and also getting rowdy. Its close spaced blocks and fast rolling center is about efficiency and comfort. It gets good sized side blocks for excellent cornering confidence which manage speed and off camber sections well. Special endurance compound for excellent efficiency on longer wear times.

Choosing the right compound and casings
MoPo Compound - Softest compound 42a, has excellent damping characteristics and reaps traction in wet slimy conditions
Control - Balance of MoPo compound with more durability and efficiency, still excellent grip in the wet
Endurance Compound - Not as soft as the MoPo but does extend durability with a 50a/56a dual compound. If are killing your tyres in a few rides, the Endurance is probably the better choice.
