I've been very happy with some 25ft rolls of .404 semi chisel China chain which is GB-evoII. Sure China chain does stretch but I've found its much worse in Picco chain compared to 404. I've given this stuff hell from high output saws in Aussie hardwoods & the chrome has held up well & the stretch has not been problematic. I found the chrome much thicker and doesn't wear off the top plate compared to the smaller pitches. Just my 2c, obviously not all China chain is the same quality but they has certainly lifted their game in the last 2-3years big time. Bill ought to put a loop of his .404 on a 2100 & buck some wood, that's the best way to know what you have & how good/poor it is.
