Aye, I think the angle is deceiving, the 224 has the same HA as my 223, at 64', though the evo has an extra +/- 1', so it's probably sitting at 63', so fairly slack still!
Depends what the track is like i guess, they can be steepened/raised or slackened/lowered with the shock shuttle. 64' is pretty good for a downhill bike though. I think the Mondraker Summum is something silly like 61'?!
