Hi Jim,
I’ve joined your Strava group.
I’m based near Reading and know the Chilterns area south of the M40 pretty well.
I’d probably disagree with what is said above at least for the area south of the M40.
This area of the chilterns is full of bridleways and miles and miles of good CX trails, but in my opinion there arent actually that many great MTB dh’s.
“I suggest getting an OS map and just explore.” again this good but I have wasted alot of time exploring trails that turn out to be boring fire road.
In my opinion the best way to ride the chilterns is
Summer/Dry Weather – 29er Rigid with very light quick rolling tyres. Quickly
buzz between the best bits of trails. The rigid bike, makes the fairly tame trails more interesting.
Winter/Wet Weather – dont bother go to Swinely/Cannock/Elsewhere or for a road ride instead.

Here is a route I did where I took in alot of good trails ->
route 1
This is a route I did which took in Grims Ditch which as you say is good
Route 2
This is a good example of some Routes I like to take in on my commute home ->

Ok some DH’s I like
This includes the Up but the DH is one of my favourites in South Chilterns
Nuns Gulley good
Is a footpath but my favourite descent in the south Chilterns
Grims Ditch
Very Difficult Climb guess would be Good as descent mind
Quite difficult to follow this the whole way but good and varied
