08-09 , I had the original 2007 and a 09-2010.....crazy fast and stiff\light board rails like no other but also easy to break.
I wish they still made them... I love my T7 and ride it on anything, but I've been getting a lot of topsheet cracks lately. When I go over a rock it may only take a couple mm gouge out of the base, but it transfers that energy right through the core and will badly crack the topsheet.
Still it's been a very robust board considering what I've done to it (I tend to land very tail heavy).
