A question - in multiple posts you guys are grooming into traffic on the left hand side of the trail. I'm guessing there must be a reason for it, but can't figure one out for flat ground. (i.e. on hilly sections you would be wanting to push/pull snow back up the hill)
I groom silly side first often as well. I take it akin to walking. Im going 6-9MPH sleds are going faster. If you were walking down the trail where would you be.
Now with all that said my drag is 10' wide, my pulling unit is bit under that. side of the trail is a moot point.
my silly side approach is usually leading and lagging on corners and it is a seat of pants decision based on what i see. on the ski course im thinking about the skier and their stride, on snow machine trails it is a process of getting the snow back where it needs to be. It is either plowed to the outside by the skis, or thrown there by the track. often times depending on the previous corners and flow of the trail. to that point some corners gain snow from braking into the corners and carrying snow to the apex.
you used the hill analogy and that is spot on.
Arly is making seat of pants calls based on experience and trail interpretation. The Bill nichols trail is a fairly wide trail bed, we don't have that to the south, we are twisty tight and thankful for permission to used the segments we get,
