Interesting because I also own and love the One K MIPS, but my Ovation schooler is dead and I was wondering if the TV would fit my head shape. Sounds like it probably would.
I bought a Charles Owen MIPS helmet last year and it gave me such headaches (thing weighs a ton) that it ended up being one of the many bad things about 2020. It was professionally fitted and everything.
If you like the look of the Samshield, the Tipperary Windsor MIPS helmet looks very similar.
