I feel finding 1 persona makes sense since otherwise you will have a messy time trying to build too many things. However, I also think selecting that single persona too early will hamper you more than messy building will. So its a balance. You have to do a wider search in the beginning, which will involve a few too many demo builds but once you find that single persona that feels like it can lead to big growth you stick to it.
