Does anyone have any real evidence that a loose track spins easier?
Because i've heard a lot of stories about this, i.e. it's a magical cure for hyfax wear, it will make your sled go faster,etc. and I don't believe it.
As long as the track has a little bit of slack when the suspension is articulated to the extreme, it doesn't need to be any more loose. Maybe the Yamaha spec is too tight, but "run it as loose as possible" is equally bad advice.
When you are riding, your drivers are pulling the track tight from the front of the hyfax where it touches the snow, over the rear idlers, to the drivers, leaving all that loose track to bunch up at the front of the rail tips.
When you run loose, you are wearing your rail tips, wearing your drivers (whether stock or otherwise), making it easier for your track to jump off the rear idlers, and possibly wearing your track, tunnel, and heat exchanger more by letting the track balloon and hit the tunnel more often.
I welcome differing opinions

You seem to be under the impression that facts, scientific principles and objective data are used to support many of the widely held opinions in the sledding world. I'm affraid you're in for a life of disappointment.
I agree with your assessment. Loose or tight the force normal to the skid that is responsible for friction and wear on the hyfax is the reaction force through the track in contact with the ground. A tighter track is going to follow its intended path more closely and require less energy to do so.

loose will slow you down, cause the track will balloon under acceleration.

I agree with you folks but, yamaha's specifications of 20 pounds is way too much. I put on a 4th wheel kit and eye-ball the tension on the track when I adjust it and also found the Hyfax will stop wearing quickly after it is half worn. Then the Hyfax seems to settle down and last much longer. In the past,I was replacing the Hyfax too soon and to often. RS Vector ER.
