First I would suggest asking over here The Ironman Training Thread 2024 - #38 by pstalley there are some fast guys/girls that visit that thread. The number of people targeting sub 9 is pretty small and your thread title isn’t likely getting their attention.
I haven’t looked at the new plans, I had used the 70.3 plans up to 2022,. I didn’t like the run sessions, the swims were okay, but having a strong swim back ground, I found alternatives that I preferred that were like swim team practice.
I raced my 6th IM last year, used a different company’s plan, the secret sauce of training plans isn’t the plan, but if can you do a plans volume, appropriately recover, and hit all the workouts consistently. I think the new features TR is bringing will make their plans more enticing as a complete package when I return to racing in the future.
