Yo, matty I've upgraded each year with the 9 and 11 combos since their release apart from 2012 to 2013, just didn't feel the need after testing, the 2011 was a huge leap from your model, bigger boosts lighter bar, better depower, much quicker in the turn and on the water, they dropped a few struts and lightened the construction which makes it drift better, its still not great in the waves but a lot better than the 2010s mainly down to the depower, my 11 is my fave kite out of my edges especially in the boost department, if your looking at getting a 2013 id consider the new 10mtr as it'd be the perfect size imo , I bloo

dy love my edges
