Stall/spin and ground reference maneuvers

I must be at risk! As I think and do it a bit differently to most here.

In the circuit I trim for landing speed c. 50% above stall speed + c. half
the headwind speed. In still air in my 27 this is 52kts and in a gale it
could be 70 or 80kts. Fast is good unless in something like a Duo going
into a small field!

In the UK we are taught not to fly a square circuit, we lop off the
downwind corner to keep us closer to the airfield (less downwind) and keep
the landing area and reference point in view. This tends to induce a
curving base leg anyway.

I aim to get at the final turn between 300ft and higher if windy and I put
in a steeply banked final turn. The steeper the bank the harder it is to
over rudder into a spin. Probably impossible at 45 or more - Chris Rollings
would know. It is also much harder to stall requiring a lot of elevator.

From the point of starting my final turn to landing I am pretty much
focussed only on the reference point and the airspeed. Keep the airspeed
pegged and use the brake to arrive in the right place.

This close to the ground it is pretty obvious if you are slipping, which
could of course be intentional. If you are side slipping on purpose you
probably don't have enough elevator to stall.

Should I give up before I kill myself?
