Well the 47s suck balls most of the time kinda like 49 iroks. I've cut mine like tsls and they are better but still suck. I would take a set off boggers all day long over these. That's what I took off and put on these. I was at Harlan a few years ago and went up cream puff with my boggers no problem and then the exact next week I had brand new 47s and there was no getting up it. But if you get the air pressure below 10 on my setup and it bits **** will break
