Of course. Use what works. Personally, I've never been able use measured moves in any of my testing with any reliability, and so I don't bother with them. And, as his book shows, Brandt didn't have much success with them either on balance.
Regarding Fib levels, I find it curious that sophisticated institutional algos would trigger there and that they would reliably continue to do so again and again over time. It just seems so unlikely in the grand scheme of things. But if it somehow works for you then little else matters.
