Just installed 144 1.25 extreme max carbide tipped studs. Well priced and have a bend or break warranty for 2 years so I figured I try them out. I skipped my 17 34 and 51st row so I wouldnt need another bag of 24 just to make 153. I went for a little ride on the ice because the snow is pretty much all gone again but what a difference!!! This is my first sled that I stud and now I cant figure out why. Second best mod, my first was the ods clutching. Thanks to everyone who recommended studding in all their posts. I searched alot and read alot and decided so many people put it in their top 3 mods list and I love them.
