I am a 155 guy but took my wife's 174 out on a little sh!tholin day with a buddy on his 155. It was really deep. It was like I was riding by myself all day. I have so many pics of him stuck and still poke fun of him to this day. So yes I agree that they can't ride if a 155 has to break trail in the deep. I said before that you have to ride like a retard to get one stuck. The problem is I said that with my wife there and she did get it stuck a few times. If all you ride is super deep snow they would be great but they take the fun out of it. It is more about how than if or when. I don't want or need it easy. I will also admit that they don't seem as long as they are. I only had a couple of times where it was too long but they have enough traction that you can work something else out. Each to there own but I will stick with a 155.
"It doesn't take the fun out of it" it takes you to the next place/level. What it must just be is you 155 guys haven't seen real terrain cuz what do you do when " we're going over that hill" to start the day and the 155's absolutely just won't make it. Haven't you rolled up to a hill in 2'+ amd noticed you weren't going anywhere. Btw I haven't seen a 155 sled break trail, that wouldn't last but for about 5 minutes. 155s are always the sleds bringing up the rear.
