Wave Grenade kinda reminds me of the German stick grenade. Takes me back to
Medal of Honour: underground on the PS1.. (That bonus level, Panzaknacker


)
Stick grenade irl, better run chaps, this guy looks like he has a strong arm!
Anyway good review qldnacra, never mind the fusspots nitpicking your scientific method.
If your weight comparisons are accurate that's a pretty big difference, and when you continue knocking a few hundred grams off each rig component the end result can be light years ahead...
Why do NP make such light masts, yet build sails that weigh a tonne? funny buggers.
