NMR spectroscopy would be the most useful method to solve the structure of a small, soluble protein that does not form a repeating structure easily. NMR can detect the small differences in chemical shift caused by the interactions of the protein with its surroundings and can provide information on the three-dimensional structure of the protein. It is particularly useful for small proteins and can work with proteins in solution, making it a good choice for soluble proteins.
