Yup it feels very sturdy while that mount

looks like he did a great job on it, mine is in front of me on the same side as when it is below its gonna be dragging behind anyways so the rod behind you is still not getting tangled when you drop it down. i want to say i have a 4lbs ball on mine...i think... but it trolls fine at 50' or so. I can't remember using it lower than that besides to get some underwater footage (mounted a gopro to the ball to see what checked out my bait

)
I will say 2 things that you will notice and maybe someone here knows how to stop at least the first one;
vibration in the line that is actually audible, while trolling i could hear the line humming and if you touch it you can feel it. Not really sure if that is normal or not, i as well ran it on super heavy braided line on top of the cable. not sure if maybe a heavy mono would do the same or not, maybe DR Steelheadcatcher knows more about this because i went to his post while researching mine.
Second thing is kinda unavoidable, you will notice your dragging around a lead weight lol. I had the tear-drop looking weight but i think if you got the ones that are skinny fish-shaped ones it would help a bunch as far as hydrodynamics go.
If needed search "downriggers" and youll see the post i did that has a few more pictures i think (in fact i better make sure the links still work)(nope had to update the links for the pictures again) but really it is just as Grizz said (nice work Grizz!).
LAstly DEFINITELY cut the arm down, if not, thats when it will lose all its stability as that arm being so long throws some serious leverage! but again, Gizz got it right
