No real reason other than braided hose will require a lot more mounting clips that means drilling more holes, I also wanted to try to keep it stock / clean looking.

From what I have read, it seems 45deg double flare is quite easy on the steel copper alloy tubing that Backdraft use. If I upgrade to Stainless Steel tubing, that's where the super expensive ~$300 flaring tools are needed. But I've never tried either, so don't know for sure.
I just found out that NAPA sell pre-flared (with ends) steel copper tubing in just about any length you need for around $10, then you just need to bend it with a bending tool. So I think I'll try that route first, and if I mess up a few pipes, I'm not out much.
Now I just need to think about if I'm going to stick with a pull slave or go back to a push setup.
