Now, let me finish before you call me an idiot. I have run everything Woody's has made for studs. The MegaBites are a lower budget, lower quality stud to compete with Stud Boy. The Gold Diggers are the most durable carbide stud, but the most durable stud that is out there, IMHO, is the Wood's TNut 30 Deg Drag pics (Stop Laughing Please, LOL) The attached picture is of these studs with over 2000 miles on them, including all of my trail riding and a summer's worth of grass draggin! The pic. was taken just before I switched over to new pics and Chisels for lake drags this year!!
