I have a pro on 672 and ive only run leeful v6 3 times in 3 months as i just suspend play mid game Ive never had any probs and I play every day as long as you use HEN as most of the hosts carry an old bugged mira that wont suspend.

with 70% chance of successful exploit like @BigWadger just said, it will be hard for me to decide to upgrade my ps4 since i already have 12TB of games it will be pain to installed it all again from scratch if my harddisk got bad sector due to kernel panic
i used p5howar exploit and i have 99% chance of success
