I have noticed that alot of sledders use studs. Why is it that nobody uses studs in the central provinces?? I can sled all year and not run accross anyone with studs but when I am online I see a lot of people are using them. If you want to run a deeper lug like an 1.5" for cross country traction than studs can not be used.......or can they?? What are the pro's and con's on studding?? If someone can fill me in I would be gratefull.
