Hi everyone, I'm posting this out of pure curiosity as I don't have an iPad Pro 9.7 (happy with my Air 2) but I wanted to know your views. I quite like the Air 2 leather case. I wanted to know your thoughts around the pro silicone back/Smart Cover and the leather case. - Which is better - leather case or the back / cover combo? - which is heavier? - is the back (without the cover) heavier than the leather case? - what's better to hold? Thanks a lot!
