Sprint Samsung S5 SMG-900P 5.0 OA6 Rooting? topic

So I have done a LOT of reading about rooting the Samsung galaxy S5 and am a little weary of actually rooting since the posts are old and so many people are saying CF (trips Knox) and Towel work/ don't work. I also realize that the two methods are not the only ones out there. I just received my phone like 4 days ago so I would like to not brick my phone. I just received the 5.0 update. I understand that rooting doesn't trip Knox but the custom recovery and roms do. Basically, I would just like a confirmation of what is the best and proven method of rooting my phone. Any help or point in the right direction would be greatly appreciated. Thank you in advance.
