Cheers for all the tips.
Review for those who may do a search:
Cannock is like Thetford on Hills. Admittedly not massive hills but it makes the most of what its got – like Thetford. The Follow The Dog (FTD) is a good intro to some intermediate without being scary trails. Theres enough in the forest to have a blast for a day or 2's riding, and practice makes it even better as going fast it what its all about.
Most of the sections are well laid out and surfaced so as mentioned in posts in this thread, unless animals are pairing up summer tacky tires will be all you need
There is loads to explore and the new trails look like they should be winners too – but as they say dont ride them till there open, these places take a lot of time to put together and if you haven't put in some work dont damage stuff others have or you're a c*ck.
All in it was a cracking ride, and if had more time would have stayed longer!
