06-07 murrays had some QC issues, I went through 2 pair, and the shop that replaced them said that they had seen a ton of pairs warrantied. Might want to go with the 08' if you do anything...
yeah i say go the murrays. Yeah i have heard that the 06/07 murrays have had some problems but that is why there is the warranty when you fork out that much for something and it breaks you would want a new pair or the newest version.
