If you really need extra protection I have my 15'2 Ti tucked into a Zero Halliburton case and I've never felt better protected. They can be had for about the same price as the Brenthavens if you shop around I found mine at a Yahoo store for 160.00. My kid dropped mine off the back of our Explorer and although the case was scratched the contents were safe. You should have seen the look on his face when I just smiled instead of yelling like a banshee. lol According to my measurements the 17" Al will fit in the Z5, but if you need extra room you might want to step up to the DZ7.
