Call me a wimp but I quite like having the side screens up with no hood. They don't rattle or make any noise and it's just a bit quieter and comfy to drive. If it's T shirt weather I sometimes remove them and use the tonneau cover when parked up. It is possible to use the tonneau with the screens and just tuck the edges in. Never tried just hood up with no screens but I imagine it'll flap about a bit.
