PKPF I was basing it on my experences ferrying planes for maint down and back to DND from INV 1-2 times a week for 18months.
I was either don't go or A9. Did the east coast a couple times and ended up at sub 500ft dodging ****e hawks. At least with the A9 you have a chance if the donk goes and you can follow the road to stop you getting caught in blind glens
