No matter how thin the flag, you find a huge drag on the cloth in any breeze.
The longer the staff, the harder it is to control.
An 8 or 9 foot staff can be managed single handed if there is no breeze, but if you go for a longer pole - anything above 10 feet - and it gets tricky. Also, longer poles bend (and can break) if it gets really windy.
But lovely looking figures. Nicely painted and based.
