Just bliss , having a weekend for myself !
So excuse me if I go a little overboard.
Looked up Heol Spars and found this on their webpage.

Wing 150 is very close to being a (carbon) copy of the AHPC Alu superwing mast that is used on 95% of all alu-masted F16's. The superwing has 1.6 mm wallthickness and so their 2 mm comes closest. I would personally be a bit hesitant with the 1 mm carbon walls on a F16 but composite masts are not my speciality.
1.2 kg for the 2 mm thick Wing 150 makes for a roughtly 10.2 kg F16 mastsection of 8.5 meter length. At least 5 kg lighter than a lightest superwing that I have on my books..
