I had a 2007 (medium) up until 4 weeks ago when it cracked. I don’t think 2007 was a bad year for them and it had done 4 years of riding including the alps twice and UK DH days. The crash also appeared after a hard fall.
They are great bikes, so much fun and an absolute bargain second hand. You do take your chances though.
Mine cracked on the toptube near headtube, mates (2007) cracked on bottom of seattube, another mates (2008) near the shock mounts.
