Everything depends upon so many factors. For example, your atheistic preferences, plain or both functional and pretty? The type of toy you will be using the harness with. The size as in diameter of the base of the toy. The weight of the toy, a heavy toy would require a more substantial harness than a small light toy. If you have or are going to acquire one of the "harnessless" toys you can or perhaps I should say you should use a harness with it for more stability. Good Luck and Happy Pegging! less
