Otter Wild vs Pro Sleds

Can someone please tell me the difference in these two sleds? I can’t seem to find any info on the wild. Is the wild just the predecessor to the pro? I am looking at buying a new sled to tow behind my machines and both of these I have been able to find in the kit with the hyfax kit, cover and hitch so they are the ones that I am looking at. Obviously the Wild kit is a little cheaper but not by much so if someone could explain the differences between them it would make my decision much easier.

check out there new website and you can compare them. The sport sled is not as tall as the pro. I would think the sport sled would be something that you would pull out by hand.
