I have a 15" 2011 MacBook Pro. I was looking for a hard case that would fit snugly (but excessively tightly) and has reasonable flex protection. I have narrowed my choices down to three options. Price is no object. 1) Thule TAS-115 2) Booq Vyper M3 3) Booq Vyper M3-GTR Which of these do you recommend?
