for what its worth, I would prefer an engine with great bottom and mediocre top as opposed to an engine with a mediocre bottom and a great top.... Its much harder to make a clean pass at the very end of a straight as opposed to pulling ahead out of a corner... IMO a engine is useless if its only advantage can be seen the last 10 feet of a straightaway.... having snap to clear jumps and taking the holeshot out of the corners to me is exactly what is needed in offroad........ However of course I would prefer an engine with a killer bottom and a killer top end all in one, but if I had to choose I will take bottom end over top end any day unless all I was doing was top speed runs.....
