When to retract the gear?

[Rickskymaster]

Since I am new to the Skymaster ownership, I have heard a couple of different ideas as to when to retract the gear.
The first holds to retract as soon as positive rate of climb is established.
The second states that because of the gear doors openings etc, and the drag created, that at least 500 feet should be the point that the gear is retracted.
I have to say that I have tested both and it seems that number one wins out from my point of view.
I am very interested in what the rest of you all do as SAP, and I think this might be a potential discussion for the get together latter next year?
