Stab line has gotten good, Stinky isn't bad (now the stinky deelux I think is basically a 2002 stab)

For a little history holligan. 2002 was roast, chute and stuff. Only diff was more gussetts on the chainstay of the roast and chute which, in theory, made the bike stronger.
2003 they made the hoss which in reality was the 2002 roast/chute frame and used the exact same geometry to make the stuff (dj series) smaller. Same bike, just small. They did this because big guys, like myself, were buying the roast because it was tough and had a fr geometry. When in reality kona wanted these bikes (roast and stuff and then 2003.5 the cowan) to be for djing and fr. So they split the line kept one normal sized (hoss) and shrunk (stuff) the other. (they even advertised this point in the early 2003 catelog)
2004 I think are the same (I could be wrong) but they still look the same, just different sizing. Again same reasoning to 2003.
2005 there does seem to be a slight change in the way the tt is welded to the downtube and how the headtube attaches. But really the change seems small.

The bikes can both hande the same loads they are just advertised differently and are different sizes. The old 19" roast in 2002 was a real 19". The 2003 and 2004 roast in 19" is tiny.
The only thing I am not sure of is if they continued the enchanced chainstay into 2003.
