Rotational mixing is considered a prime candidate to explain the gradual depletion of lithium from stellar photospheres during the main sequence. However, past mixing calculations have focused on limiting cases of stellar angular momentum redistribution, assuming either solid body rotation or pure hydrodynamics. Instead, various lines of evidence suggest that stars are highly decoupled at young ages, and some unknown AM transport mechanism re-couples their core and envelope during their MS lifetimes. We present mixing calculations which include a constant diffusion of AM from the core to the envelope, in order to assess its impact on rotation and mixing as a function of age. We find that such hybrid models are efficient Li depletors at intermediate ages (\(\sim 500\) Myr), and inefficient depletions at late ages (\(>2\) Gyr), in good agreement with the observed open cluster Li depletion pattern. Furthermore, we find that re-coupling models are able to simultaneously predict stellar rotation rates at intermediate and at late ages, whereas the aformentioned limiting cases cannot. We conclude that core-envelope recoupling strongly out-performs limiting AM transport cases in reproducing observations, and is thus a promising paradigm.
