Well considering the Shocker is made in Canada and the M6 is made in the US, how is this comparison pertinent?something to consider comparing US made vs. TW made frames
most US made frames are 6xxx aluminium alloys (including Easton and Worth tubes), unless the bike co. has specifically imported a tubeset from TW, for domestic fabrication
most TW made frames are 7xxx aluminium alloys (apart from low end frames / bikes)
compare the properties of both these alloy groups, the 7xxx takes the win in every category including strength, toughness, fatigue life
frame made from 7075 will always be stronger / tougher than same frame made from 6061
