Ok I read what you say and you have clealry stated that the MT21 is a bit too off road for your needs in which case I would strongly reccomend the Metzler Tourance's as these tyres have outperformed all other tyres that people have used for the XTR because they offer good off road as well as tarmac performance due to their perfectly designed tyre pattern which gives the best grip but also a phenomenal rolling resistance on tarmac which truly suprised me when I tested an XTR with those tyres after having tried one with the Syrac's (which are no way near as good imho)

Only recently Motonacio has fitted a set of enduro Distanzia's we don't have yet a full performance report from him so when we do we will know if the Distanzia also work well for enduro bikes (I don't see why not)
