[Closed] Tyre combination for mixed terrain

By now with the terrain I usually ride on (moorland trails, a few rocky sections but in minority) Im riding Schwalbe Black Shark mud tyres until spring next year. However if Im going riding in rockier terrain, still with some soft ground sections what is best tyre combination, mud tyre on rear or front tyre? And what about the non mud tyre choice (Ive got selection of Pracer Razers / Kenda Karma 2.0, KK 2.2) if I just run a F?R mud tyre? Or is it best to stay with a full mud setup despite the rockier elements
