to tall for Large Epic Expert 08?!

hello!

my name is Klaus and I fall in love with the Epic expert 08! My only problem is that I'm not sure about the size. I'm 189cm (6ft 2) and it seems that I'm between L & XL. I'm quite fit and I ride at least twice a week but I don't really want a race machine (and have a sore back after every ride). & I love uphill, therefore I tend more to an XL but I' not 100% sure yet. Anyone any advices, suggestions?!

thx in advance
Klaus
