I've been running an Army Special front, C-02 rear for most of the year, which is an OK compromise for something that gets used on the road in between rallies.
In an ideal world, I'd buy another front wheel and use a proper open-pattern enduro front, at least for the muddier rallies - Ryedale, Beacons, probably Hafren. The ones that are mostly stone/gravel based the Army front was fine.
The C-02 rear works great, a lot of the Big Bike lot use them.
E-09/TKC not aggressive enough for rallying IMO. Fine for trail riding.
Oh and just stick a cheap high mudguard on
