You must have a reason for doing this in a complex type, not sure what might be, please do tell. Teaching ab initio flying in a complex type heightens to likelihood of it all ending in tears, I'd have thought.
In the UK, we set great store by using a checklist, especially in complex types. Our after-take checklist would include undercarriage raised. The call is generally 'no usable runway remains, positive rate of climb, brakes on/off, undercarriage up'.
The pre landing checks we teach are
Brakes off
Undercarriage down
Mixture rich
Prop fine
Fuel sufficient for a go-around
Fuel pump on (if called for in the POH)
Flaps as required
Instruments - in the green
Harness secure
Hatches closed
Height as required - a great reality check
Heading as required (at this stage, normally reciprocal of runway, another great reality check you've got the correct runway)
On final of course,
Red - Mixture rich
Blue - prop fine
Green - confirm undercarriage down and indicated
White -landing light on
