Kranvagn crew skills question

Hello guys! I'm close to getting the Kranvagn and I'm not sure what to choose as 4th skill on my driver. I use a female crew and besides Sisterhood of Steel, I have Repairs on all them them, Sixth sense, Snapshot and Smooth ride.

I have reached the 4th skill now and I'm thinking either Clutch braking (because some traverse speed never hurts) or Off-road driving, since you tend to go on ridges alot and the acceleration might help aswell on ridgeline peeking and retreating.

Thanks in advance

Edit: Offroad driving it is. Thanks for your input.
