I would like to try it too. There have been a few threads on here claiming Stihl has discontinued sales in the USA, but I don't believe everything I read here.... Brett has some ass kickin chains to go with his Smitybuilt powerheads.I bought 100' of 63ps for a friend after he tried a loop I gave him. They love that stuff on 14" 200ts. I asked him to try it on a pole saw but have no feedback yet.
