Odd, one thing I read (on spoke junkies) said Phase II was more technical.   
Going fast on a few of those sections was fun!   
I made it over just about ever obstacle I saw, went out of the way to go over them!  One I knew was out of my league so I didn't try.  They even had a little tree ride (? where they take a tree, cut it in half, stick it lenght wise and you ride on it).  I just about fell off when I first got on it so I was pretty pumped I made it over it.  A few large obstacles (think trees stacked on trees with trees leading up to them), I didn't get over the first time.  But I turned around, got in the right gear and went at the right angle of attack and got them the second time.   
I didn't make it up a few of the very steep sections, wrong gear sometimes, didn't have enough weight transfered forward, lost my momentum and lost balance sideways.  I'm sure I will get them with experience though.   
I'm sure you are more busy than I with a wife and triplets, so let me know when you would like to go and I can try to make time.    I'm in ok shape right now, I'm sure you won't have a problem keeping up with me.  Anyways I have no problem with slowing down a little bit if need be, I'm sure there are plenty of technical things I can learn from being around someone who's done this some.   
I wasn't quite finished for the day yet, I wish I would have known that Phase II was 'faster' (less up-down-up-down I assume) I probably would have went and done that too.  Probably for the best anyways, I have other things I should be doing later.
