Different set up
That appears to be an entire secondary set up. Mine was the Heel Clicker unit that bolted onto the stock Yamaha secondary. Maybe your set-up works a little better as it is an entire unit. I just find the button secondary to be much more consistent as snow conditions and temperatures change. Personal preference also has a heck of a lot to do with it. Personally I am willing to trade off A LITTLE backshift for consistency and increased top end performance. It's all opinion and that's what this guy is looking for so I think this should be valuable information for him.
