Which to use?

Honestly, it doesn't matter which method you choose, as both achieve the same result. In a lot of cases, a mixture of using both ByTypes and substitution is the best option: you could specify a unique texture for a more unique variant, but then use substitution on all of the other variants. By using the ByType method, you could choose to have completely different handle textures, however the substitution method offers considerably neater and shorter code.
