I have been using an extra Karakoram clip in the center of the board on my DIY board as well as the T.Rice I have had for the last 2 years. I also always use the pin between the touring brackets to add tort ional stiffness. I think the pin has more support.
I call it the sheer effect. I have posted a few things about this a few times. I now use small S.S overlapping tabs to keep the 2 halves from separating even on my new Jones solution. I posted some pics on a DIY Skunk Ape thread here a while back if interested in checking it out. I am not at my computer right now so I cant attach a pic.
The S.S tubing or pin I use through the touring bracket is just a piece of stainless tubing I scraped up from work. It works great and is light weight. I can find the exact size if anyone is interested. I think its 3/8ths"
I don’t like that sheer effect and have some ideas about how to stop it completely, without adding much weight. For now the tubing has the most effective performance.

I have not used the pin through the brackets, nor is this a comparison between the two.
I'm suggesting that you actually do a comparison, for the benefit of the rest of us! Especially since you said it's so easy to get material for a pin, and you're a board builder and eager to modify your boards but most folks aren't gonna drill holes in their boards just to test out a theory.
I suspect that there is not much difference between the two methods in practice, but I could be wrong. I've used the pin a bit, and it definitely seemed to help in the steep and icy shit that I inevitably end up in when I thought it was gonna be pow. It seems that in some ways it could be better because there is effectively more overlap of the board halves vs the 1/2" from the split hooks. The one issue I ran into was that the torque of the pin on the bushings in the LT brackets caused them to loosen. Might not be an issue with brass bushings.
Ah I gotcha! I was just trying to make sure people didn't see this post as a comparison, or saying one is better than the other. My hesitation with the pin is the pin bending under heavy and un-planned stress, or damaging/loosening of the touring bracket. In the past I have experimented with different attachment methods on the touring brackets (heli coils) and had the brackets pull off while touring. After walking back, I personally don't want to add even a hint of the possibility of damaging or tweaking my touring brackets! haha
With that said, I do not have any issues doing a direct comparison test. My team mate just got the same deck that I am riding for next season (the only difference is the graphic). If I can convince him not to do the extra hook straight away, we can do a comparison between the two methods. I suspect that the performance part will be very similar, but of course, nothing shows that better than a test!
Also if anyone missed it, the pin size is 3/8 and FirstLight (company and username) does sell the pins ready to use
