i leave mine in 4a as it moves power around when needed and may give a little handling edge even on dry pavement in corners it stays there rain snow dirt roads grass fields and dry rds of course ...i off road often and do use 4h 4l and even goats modes at times
i just feel 4a is when i dont...
yes 4a is the set it and forget it mode
i use it exclusively in nj for the extra safety and grip
ps
watch your message read out of power distribution ...it shows its working all the time
