Question - roll up screen and ceiling netting

[Captargo]

For those with roll up (sportscreen) setup, looking for feedback and advice on how you hung and or attached your ceiling netting so no gap or ability for a ball to get behind the screen. In one post , one person had mentioned that they velcroed the ceiling netting to the top of the impact screen and that worked well.
thanks

second question in addition to the one above about hanging ceiling netting
do you have anything covering or protecting a direct hit on the roller?
