Abliteration techniques might be more limited with reasoning models. I don't know if they process simply be rehashing the arguments or if there's more under the hood that would be harder to alter.
I try new models from time to time, including some of the thinking ones, but I've always come back to the NeuralDaredevil model, even though it's "old". Your results may differ depending on the subject matter, but I can't think of an instance where I hit a wall. At most, maybe some sidetracking but once I told it to be more open it didn't hold back.
I'm not sure what the appeal of the thinking mode is. Perhaps on some things it does better, but in watching its reasoning I've seen it talk itself out of a good solution too. Which is what you get with typical models when you push the context too far and don't start a new session, they wander.
