Just use Oregon chains although the ones you asked about are probably made by Oregon. Roger
......R, thank you but, there are now more options than Oregon....e.g. Carlton and Silver Streak,,,and probably others....I used Oregon all my life,,,but, I do realize competition bring new technology.....As long as it doesn't come from a pacific rim country(China,Korea,s.e. Asia,etc..) I'll take a look at it...Dan
p.s. I called Oregon/Blount yesterday...The customer service person had no idea about Silver Streak...Found out later Silver Streak is owned by the Stens Company.....called them a minute ago and they confirmed that Silver Streak is made in China and comparable to Oregon...Also found out that Carlton(USA) chain is harder(rockwell) then either SS or Oregon....
