I am sure the 24 scratchers work better than the older Holz style ones, but are they the only or the best answer? Hmmm... let's compare paddles...The 24 scratchers work stellar. Mounted farther forward, big paddle on end plus they are twisted so the paddle is angled and throws snow towards sled. Even loads running boards. They do work. Lead a horse to water but you can't make them drink.
