The Pax Bellum is awesome. I'd only run it about 5-6 hours per night. Otherwise, you can strip out too much of the nutrients and stunt the soft coral and LPS growth. I do have one, so I'm speaking from experience, but I'm not using it anymore because of the seahorse display refugium I set up.
On the torch, unfortunately, you're going to have to learn to be ok with it. I picked up 2 heads of an amazing gold torch locally and one died a week later. Nothing else I'm my tank had any issue. It just disappeared over about 48 hours. Went into the LFS where I got it and the remaining heads were about 1/2 dead. Some corals just won't make it. It's sad, but you can't always blame yourself.
If there's one thing I've learned in this hobby, it's that I need to be prepared for disappointment. The highs are really high, but there are a lot of things that don't go like you want them to. If you can have a mindset that helps you roll with the punches, you'll really enjoy it more.
