I had worn my hy-fax down in about 500 miles. The sad part is that I watch where I ride and try to ride in good snow conditions.
I added 6 Excell wheels in the location as shown in the pictures.( Wheels with the X on the outside). I then added 2 Yamaha wheels just rearward of the front curve, and 2 Yamaha wheels rearward of the Excell wheels in the center . I made special mounts for the Yamaha wheels which lowered the wheels down .100. I now have a total of 10 wheels not counting the rear wheels.
I then installed new hy-fax and rode about 180 miles in very marginal snow conditions at the end of the season. I did not notice any wear of the hy-fax during that time. The hy-fax would have been half worn down in those same conditions.
I will do more testing next season.
See pictures below.
