[disclaimer] I don't recommend any modifications to your bar I have done for anyone, let alone beginners. I just prefer making my own lines and ended up with a few other mods.
My final Liquid Force above the bar swivel broke when I was facing backwards just after boosting a big frontoll in 18mph on a 12m kite and racefoil. Kicked the board away immediately and got as vertical as I could and suffered no damage probably 30 ft up I'd say.
I hated the switch swivel, it doesn't work under load. If you look at the switch swivel construction I can't imagine the strength is there either. I love the LF swivel, always worked for me until it failed. 2nd failure is enough for me as I jump constantly now. The plastic LF swivel design is a no go for me as I began thinking about a replacement. Both breaks were at the centerline of the plastic allowing the safety line to break thru.
I hydrofoil 90% of the time now so I use a Winchard 2673 instead of a chicken loop. It has worked flawless for me for 3 years. Never had an unintended release and always released when I pushed it away. I'm going to purchase another to avoid any wear related failures and use the older one on on my backup bar.
So with no below the bar swivel I need an above the bar swivel. Not to mention, it is glorious to do a bunch or rotations and never have to manually untwist your lines. I'm looking at the below linked product and wondering what anyone thinks and if they have any other ideas:

I'm considering drilling two holes in the 3/8" bolt, then drill a chamfer and meticulously sand to remove any sharp edges to accept the center lines as seen in the brass pieces I have displayed in my pic. From what I read these swivels work better under load then not under load....https://youtu.be/I5m_i_huWOw?t=9
