I don't know that paused squats are going to save you. Your problem seems to be with the ascent that turns into a good morning. If you are doing more of a good morning at 185 at a normal male bodyweight, you need to learn to squat correctly before worrying about a paused version. Video would help. What do you weigh now?
Here's the awful truth - squatting is difficult. It requires a lot of effort to hold shit together at weight and no amount of assistance work will make up for good, solid, controlled reps done with good form. Find a weight that you can squat correctly and build on it from there.
