Definitely screws. When the pilot figure gets sick from your wild aerobatics, and pukes all over the cockpit, you will need to be able to remove the canopy for cleanup.

Screws for me too.
I've had two pilots with serious whiplash needing emergency room care after nose plants.
Plane was OK, the pilot never was the same again... they will not fly any more.
