I've been looking at the new stumpjumpers and I've noticed that the headangle has been reduced from my 2006 70.5 degrees to the latest 68.5 degrees which is what most of its contempories are running ( Yeti 575, Commencal Meta5 ) I enjoy carving lines down single track with 2 foot drops and steepish sections. I always feel like I'm going to go over the bars when going down steep sections - is it all in my mind combined with poor body position or would I really benefit from the relaxed geometry?
I have to cycle for about 2 hours up fire roads to get to the exciting stuff, does the slacker headangle making cycling up hills a chore?

I would really appreciate any opinions, I think I need the new bike but I really shouldn't be spending any more money right now.
