Well its a toss up whats takes more skill, so im not ready to vote right yet. I don't know if hitting a big rock or tree ripping along in the woods and mountains or hitting a big razor back or witches eye ripping along in the dunes would be worse. All i know is that both take skill and knowledge and be aware of your surroundings, especially whats coming up ahead of you. All of them would hurt and put you down for a bit.
Ive been pretty damn close to doing both, but i honestly don't want to find out.
It shouldn't go into argument
