ROOT & OCTAVE

Years ago, an ancient civilisation inhabited the valley. They are shrouded in mystery to this day - but recent discoveries have brought to life two mysterious structures. Known as Root & Octave, these machines are powered by the Octavarium… Their secrets will soon be revealed...

Regarding the loops and headrest, I would bet that ASTM, EN or other standards have stated that if certain gs are induced in a ride - in this case forwards/backwards - it needs additional head support aka headrest.

Look up ASTM F2291-2006 and EN 13814 if you haven't already. They are long but very good reads!

I particularly find it a beautiful an looping, aesthetically speaking, it does look beautiful on the roller coaster, and I think when it's bigger and oval the experience better because it avoids certain frictions as you're saying, as is the case of the Full Throttle looping, which is tall and well oval, avoiding certain negative and uncomfortable forces, I certainly think this is one of the reasons for not doing more Vekoma Looping Corkscrew due to its tight looping, and since most have trains with many wagons, the latter must be much more uncomfortable, but still really not being of the vekoma I think the Viper one of the roller coasters more beautiful to be seen, it gives a perfect air to the park due to its location. I really like the classic roller coasters, even some having criticism for being uncomfortable.

Yeah that was the issue on Arrows in particular...though it was also the point where my head would be forced forward, not backwards. I guess if there was no headrest you could theoretically have your head back a bit too far, then the force pushes it back further particularly with the jerk there.

But on a modern loop? Easy to design without that issue and without any whip over the top like you might find on a modern but snappy loop like say Great Bear. Shape/pace/size it like Full Throttle or Dominator and I'd imagine it should be fine.
