Lightest / Stiffest Boots of 2016

Hey guys, I'm coming back from a serious injury this year so I haven't been following the Market as closely as I used to, and I need some advice on the latest gear...

I'm looking for the lightest, most responsive / stiffest boots on the market. I currently ride in a pair of Ronix Cells; but they've become too broken in...

I'm looking at the Ronix Code 55's, Ronix Kinetik's, and the Slingshot Rad's

I'm coming back from a detached Achilles Tendon and 3 broken ankle bones from a Snowboarding injury; so I want something firm and super light weight. Thanks in advance!

Also, anyone have any experience with Slingshot's Pill? I've read it's a little heavy.. but I ride a 2013 Recoil and love it, so I'm sold on the company...
