When to retract the gear?

My decision as to when to retract the gear depends on runway length and what configuration I want to be in if I have to put the airplane back down.

Coming out of typical airports in So. Florida (6000-10000ft runways) I'll hold off on the gear till I know I can't put the aircraft back on the runway.

Coming out of North Captiva which is 2000 ft with water on both ends, the gear comes up as soon as I break ground and have positive rate. If I have to go into the water, I want the gear up.

Granted I've got the gear door mod on my airplane. Back before the gear door mod I wouldn't touch the gear till I had 500 ft.
