The 08’s had issues, you could pop the spokes out of the hub flanges if you landed too heavy or had sloppy spokes, due to them being open ended. and the freehubs are generally regarded as being completely shit. Only two sets of pawls and it uses the same fluro ring at the end of the freehub body/ flange side as the kysirium ES does, ie not built for impact loads.
if you aren’t going to be dropping on them they hold up ok, suitable for all mountain, but not a DH/FR suitable wheel, even though the strengths is way up there and the rims are superb.
The 09’s however, now there’s a wolf in sheep’s clothing.. A true heavy duty AM wheelset.
