Could try raising the rear a tad Paul.
This problem is more often than not the rear squatting under power and the bike handling like a boat. (Could be handy for Gerrards around the lake)
Also, with these more rounded tyres it feels lazier to turn, but I think a couple of clicks harder on the compression and 2 softer on the rebound (rear shock) may have sorted it at Brands.
Remember all circuits are different!
Generally I like a quick turning bike and can't afford to drop the forks through the yokes any more, as ground clearance is already less than I want so would prefer ride height adjustment.
