I recently saw this video of someone who made their own "modified" version of the reflective stick balls to work with hitting a surface, such as mesh pads...

I asked the author of the video what he used to make the ball ends and this was his response...
" its the same grey stuff you find on hi-vis jackets/vests. Bit of pain to glue but worth the hassle. Foam for the ball shape was from a water noodle float

I wonder if a reflective spray like this might work, instead of tape...

Any thoughts?
