Whoever told you that going to a low caster setup is difficult to manage probably didn't have trailing knuckles, because with trailing knuckles it's really easy to get used to.
People say ackerman is personal preference but you'll be faster with less ackerman. You'll have to get used to it on the street, and your turn in will be less aggressive. If you're using it only for drifting, low or none is the way to go.

kinda disagree with most of this.
KPI and caster are making a comeback after a few years of the wisefab dogma, since you can artificially weight jack onto the rear end for more bite.
mech trail can help a little bit but you can still get a fall to angle like all the Wise fab bullshit and honestly 90 percent of people the self steer from a bigger caster number is probably helping more than it hurts.
Also typically on faster tracks we would change onto the higher Ackerman setup. like, yeah sure, on paper you'll be outright faster with less Ackerman but the inside wheel drag basically amounts to a built in left foot brake effect that stabilizes the car and is super benificial in tandem.
