You don't mention anything about pack weight. I will say that when I first started backpacking I tended to carry a lot more gear and hence a lot heavier pack. With a heavy pack every slippery spot of trail becomes much more dangerous.

Over the years I've slimmed down the pack weight, very rarely carrying more than 12-15 pounds before food & water. As a result, I don't really notice the pack on my back and I feel much safer on questionable terrain.

Just a thought.
