Cool. Thanks for that.
That's actually shorter than I was imagining.
My FX thighs are just under 15", measuring the front cover strip top to bottom. Calves are 14" measuring the same way.
My own measurements, hipbone to top of knee cap is 20". Knee to ankle is 17". I reckon I'd need thigh armour about 17" minimum, preferably 18", and about 16" for the shins.
Interesting...the forearms are half an inch longer on RT-mod though. That's useful to know. Mine aren't bad, but an extra half inch wouldn't hurt.
