Hemi- just my .02, but I would suggest cutting the bottom of the actual ball off. If someone really wanted to, it's possible that they could get something between the big lip and bottom of the tongue. Not saying it's plausible, but hey, you've already gone this far

When I was 22 I took my Grandmother to West Virginia to visit the property she had grown up on and see some family. I remember one part of the trip very vividly. Her brother had recently passed and she was in charge of his lot which had a couple park trailers, sheds and other misc. items. There were 2 paths from the road into the lot, both with gates. The people (other family) that were supposed to be watching the lot had called several times informing her that another lock had been cut. Nothing really valuable ever dissapeared, but it was frustrating, and a little unnerving as it was in the middle of nowhere up in the mountains.
When we went to the hardware store, she asked the gentleman for the best locks they had. He of course asked what it was she intended to lock as there are several different lock styles, and explained the different applications for each of the "best" locks. She told him what it was she wanted to lock and asked which one would you use. He paused for a moment and held one set out, but before letting go, he looked a little dissapointed and said "Folks, locks are only intended to keep honest people out. If you really don't want to loose somthin', take it with you or get it out of sight."
I'll never forget that as long as I live. For this reason, unless I can buy something that's nearly impossible to break into, nothing of value stays with something I let out of my sight. On the flip side of that, there is a masterlock on the tongues ans clasps of each of my trailers. I don't bother with the big circle ones that are nearly impossible to cut with bolt cutters, as I bought a trailer from a friend that swore by them untill someone took a prybar to the clasps and after wreaking havoc on the walls and clasps, got in and took what they pleased, leaving him with not only the heartache of theft, but pretty substantial damage. If they want it, they'll get it.
A few years ago I had several vehicles broken into, at my home, because I was too lazy to take the Faceplate of my CD player off (I was in highschool and college
) Ironically, the only one that never had anything stolen from it was my topless, doorless Wrangler. From spring to fall it was wide open. It of course had an aftermarket CD player and extra speakers in it, but I took the faceplate out, hid the wires and threw a raggidy beach towel over the speakers. 2 summers and nothing dissappeared. Fall of the 2nd year my cousin bought it and put on the doors and the hard tops. I begged him to take the faceplate out and leave the doors unlocked (those windows are expensive and a pain to repair!). He is older than me and didn't listen. Within the 1st week of him owning it, someone busted the window and stole the player and speakers while at his work.
Whelp, I guess what I'm trying to say is
1- Outta Sight, Outta Mind
2- Think about the reprecussions of the damage that could happen, should a less than honest person accept the challenge that we faced them with at the point they decided they better deserve our property than we do.
