I cannot understand how is your circuit. Please attach it to see what you have done.

About the driver FET, the one I select was based on price, availability, size and speed.

Remember that when you try to switch ON the Power mosfet, you try to bring low the gate. The gate is at that moment a capacitor charged at 24 volts and discharged through the small FET and the 470 or 330 resistor.

Also remember that the resistor on my schematic should be at least 1/2 watt because when the small MOSFET is ON, they draw a current of at least 16mA and this leads to power loss of 0.391 Watts!
