Hi Tinlyds
I'm not sure of the weight or strength.
I presume its all relative.
I suppose it depends if your a heavy guy like me.
I have a NP X9 225 - 265 carbon and a Unifiber 180 - 240 carbon.
Even on my 7.8 warp , 225 , I prefer the more solid and heavy NP.
But I am 120 kg and I do put a lot of flexing stress on my equipment.
Personally , I believe a heavier solid boom is better than a lighter flexier one.
However if your a light guy , its probably a load of crap that I have just waffled on about
