Complex singles

[bigbloke]

Hi

For those on here that do fly complex singles or have done, when did you move on to them relative to earning your PPL ie: learned on one, straight after PPL, after getting an IMC or IR, a couple of hundred hours in etc and why ?

I'm assuming for the purpose of this discussion that this means wobbly prop, retractable undercarriage, a bit heavier and a bit quicker than a 172 or warrior and instrumentation for IFR.

Thanks
