I'd try to open it up some. I'm 5'11",on a large with 90mm stem, and still find it short in comparison to my previous Heckler. Mind you, I'm more biased to 2-3hr trail rides with lots of ups. It's all about compromise, and what you want out of the bike for it's intended purpose.
It's a hard call for someone your size to decide on which size bike to purchase. Your right on that line between M and L. Give another length stem a go. I'd say a lay back post, but you'll never find a 30mm one. I happen to have a 60mm stem for downhill days. Ride On.
