WHAT'S THE BEST GD&T CONTROL TO USE?
(OP)
I have a spring with one leg horizontal then .072 BR angling down 15 degrees. On the paper plan or top view, the two legs need to be in line to each other within .007. Should I use profile or parallel or what? No datums.

If the top view is a circle then I'm not understanding the question.

Both parallel and profile tolerances relate the feature to some other feature. How can you not have datums?
A profile tolerance will control the actual deviation. All parallel does is make the deviation approximately constant. Profile tolerances also control parallelism.
