One question nobody has asked the OP. What forks are you running? I’ve got 160mm Zocchies on mine, combine that with running quite a bit of sag on a 57mm stroke rear means that even in the XC setting the HA is probably slacker than a stock Prophet in the FR position.
ETA steepens everything up for the climbs so no probs there.
As for getting a slack bike to turn sharply, countersteer then fall into the turn.
