Simon I think we should also reconsider non nbt rules after seeing this.
They show it's obvious you can gain time with NBT's that are not off-road, and don't require long, sharpcurves cause they are acquired with zig zagging on straights (ala MT'ing in mkdd almost)...
Or did you already state in the rules any zig zagging NBT use will automatically qualify as NBT time?
Sorry for posting 3 times in a row

I realised new thoughts immediately after posting the previosu response, and tbh. I am a bit excited about it all.
After all this could give SMK Time Trialing a new direction, not necessarily a good/welcome one tho

As far as I can see the SSMT's (i guess you can compare what they did on RR with those) are overkill in SMK.
To be continued
