Ultimately, your body, your car, and therefore your choice. 4pt is generally done away these days in competition due to shortcomings of no anti-submarine.
SAE paper cited is, for all intents and purposes, 20 years old. Essentially same ERA as Dale Earnhardt's tragic passing when HANS was in its infancy and not yet mandated required equipment in NASCAR. There have been countless safety advancements since and suspect SAE has published numerous papers and/or standards since to supersede.
Likewise, Schroth video published by "Detroit Tuned" appears to have been filmed only in 4:3 aspect ratio... same as final episode of M*A*S*H
Finally, most "restraints" other than OEM 2 or 3 point are not street legal so best check w your state DOT guidelines before installing.
Good luck and be safe

There are some good sources that strongly disagree with these points though. For example, a study done by the sae showed v type 4 point harness to be as safe if not more safe than 3 pt harnesses with no occurrence of submarining in their tests. This study assists limited though as the test numbers were small and the crash scenario was quite limited.

And schroths crash test videos with the 4pt ASM belt are impressive to watch (although I always question when a company does research that so strongly supports it's own claims)

Anyway, thanks for the replies. It's always nice to hear other people's insights and feedback.
