I am not sure where you are located. I am in Central NY and we do get a lot of snow, but some areas can have a lot more. I have not had any issues with the front end bogging down or getting through snow drifts. I am usually pulling a Clam Yukon loaded with gear and just me. Sometimes a second person. On the lakes I go on the snow usually drifts off from the wind anyway. Like any sled without studs, I can slide on the ice but I am almost always under 15mph and say in control. I did melt my track to the sliders on one very bare ice day, lesson learned about carrying the proper tools just in case. I added scratchers but they don’t really work too well. I am thinking of studding the track this year as it is mostly an ice fishing sled.
If you are going on lots of unbroken trails and back country, bigger skis will help for sure. But for my uses I have not had the need.
