Avoid a second hand 08/09 due to the crack issue.
07 is fine afaik.
Ive a 2010 one, had an 09 and cracked it around seat tube but 10 has been fine and has been thrashed for a summer in whistler.
Angles are adjustable with headtube insert on newer, not sure about 07. They do two sizes, S/M and L/XL anything over 6′ should be the bigger, if you intend on riding it as an all dayer then maybe slightly shorter riders would need a L/XL.
I honestly cant fault mine atm. Gonna get the rear shock PUSH’d but thats it. Oh i, buy some Maxle dropouts as it stiffens rear end up a treat. Now that Speci arent bringing in the SX trail this is prob the best slack 6″ FSer thats DH worthy about.
