I recommend you try many pitches.
The flying diamond is about the quickest and easiest to pitch and you usually don't need to use a pole. Just run a line from one corner to the nearest tree. You can get by with three stakes in calm weather, but don't count on it if it could get breezy.
If it's going to be cold, I will usually pitch a low half pyramid or modified A-frame to reduce air flow.
Although the lean-to variations can be great for ventilation, shade and coverage, they can be a problem in windy conditions, unless pitched against an object(Boulder, bush, fence, wall, car, ...)
Modified A-frame and some pyramid variations are some of the most stable in strong winds.
