I think you may be getting too much advice here, not that its bad but it quickly reach saturation point. Aluminium frames are generally regarded as having a five year life span, depending on thier use pattern. If you have a bike shop in your area that you think is reputable or you feel you can trust then have talk to them. Also it might not hurt to contact a couple of the manufacturers mentioned and tell them your situation and see what their responses are. I think Kona is still small enough to take time to listen to you and help out. Other smaller custom builders would be good for this too. There was member here about your size that rode a hoss deluxe but I cant remember if it was standard or not. Yes mine is standard except for the saddle pedals and now the hope skewers. Good luck and enjoy the bike you choose.
