They are not the type to overthink and ponder perfect messages.
If you usually let things marinate, do that. Don't focus entirely on someone awesome in the early stages. You can't just suggest a date in the first message; the girl has to feel like she knows you well enough to meet you, and both the number of messages and the time that's passed since you first started your conversation will help give her that feeling. When I recommend waiting, it's because it's because it's better for efficiency.
