I'm looking for rigid cases for my 6+. Something that'll add some structural rigidity to it to avoid any bending. However, I don't want the case being too thick and bulky since the 6+ is already quite big. What would you guys recommend? So far i've come up with the following, although i'm unsure if they are rigid enough: http://www.thinkbym.com/products/al13-v3-iphone-6 http://www.case-mate.com/iPhone-6-Plus-Cases/Case-Mate-iPhone-6-Plus-Tough-Cases.asp http://www.spigen.com/brands/apple/...6-plus/iphone-6-plus-neo-hybrid-ex-metal.html http://www.incipio.com/cases/iphone...with-impact-absorbing-core-iphone-6-plus.html Anyone who is currently using hard cases with their 6+, your input would be most helpful. Many thanks!
