Should I do a beginner 4WD course

[Ben-e-boy]

No.
But have done downhill mountain bike for 8 or so years in my younger years. Does that count ? Lol

But that's a very good point you've brought up. The concept of balance and line selection process on dirt bikes is foundation to how you would you about in a 4x4.

Yes very much so.
Think of the speed you need to think about putting your bike in the position you want it to be in, whether that line is going to effect the next obstacle, corner, jump or whatever on that downhill track,
It's a similar train of thought for 4wding (modified obviously), but much slower. You have a lot of time to think about it and include things like diff clearance and wheel track
