My feeling is that after reading all your earlier posts again, that you really, really, want the 2015 F6B...If you can spend the money, I would go for it and not look back...It seems to me that you are trying to rationalize the purchase of the other options in your mind and that you may not be totally happy riding the used or leftover 2013's everytime you seen the current model...Life is to short to not enjoy what you ride...If "bucks" are, in reality, an issue then go for your cheapest deal and be happy!!!...JMHO
