Galaxy s6 Sprint 5.1.1 root

So I just bought the GS6 today and I really like it so far but I cant seem to find a way to root it... I havent rooted a phone for over a year and I stupidly updated to 5.1.1 before I was sure I could root the update. I have a Sprint GS6 (G920PVPUBOGA) and Ping pong doesnt work and I cant find any root options that I am sure work with my baseband. I am not super savvy on rooting so I dont know if that matters but I wanted to make sure before I used a root option that would brick my phone.
thanks in advance for your help!
