I’m told dhf is great (I’ve just put one on but only tried it on dry hardpack where it was awesome). I think it leans more towards hardpack but ok on mud.
I’ve not tried it but magic Mary is also meant to be good – but perhaps leans slightly toward natural rather than hardpack.
Depends which you do as to which you would go for.
Both of those are for front tyres. On the back it’s up to you – I’ve stuck on a dhr2 which I previously had on the front. Feels more locked down on the back than the aggressor I had on there before – and is meant to be good under braking.
Hans dampf is also meant to be ok as a back tyre, as could a nobby nic. I’ve only had the cheapest rubber version of the nobby nic and it wasn’t brilliant on hardpack but was good on natural stuff.
