I have a 02 Z Sno Pro, I have 96 studs in it but will have to probably take about 20 out to meet the new rule (haven't checked yet). I just bought a new pair of C&A pro race ski and was wondering what the best carbide sizes are. At the race school this past weekend I bought the AC 5/8" host bar with 10 inches of carbide without hardweld. Does Woody's make the carbides for Arctic Cat, because it is in AC packaging? I don't see why the 8 inch ones with hardweld cost more, do they really last a lot longer and work better?? Can I have a welding shop put some hardweld in front and behind the carbide, or would this make them illegal for racing. I guess its a little too late for me to change my setup, but just wondering what most people run and what works the best.
