Your breaking way to much gear man !!
You must be doing some seriously overpowered sailing. X6 NP booms are a tuff stiff boom (and heavy ) take some breaking though, As some one mentioned you may be over extending the tail piece and need a bigger boom to match your bigger sail !! Have you thought about dropping sail size when the wind starts honking ?? A controlled smaller sail is faster that an out of control over powered big sail (unless your Antoine Albeau)

95kg isn't that big !! shouldn't be a factor unless greatly over powered !

Go the Ezzy's if you sail in a strong wind location, Bullet proof easy to rig " set and forget" with the down-haul , then just tune the out-haul .
I say that and I use NP cause I live in a moderate wind location, need the Mono light and responsive, But while in Maui it's Ezzy's .
Gero WA , Ezzy's are very popular not only because of thier strength but thier awesome wind range in strong wind.
Powerex skinny's are good and are used by the hire outlets in Maui for their strength , and they rig nicely on most sails.
Having the right Equipment for the right conditions should see you maintain your gear for years .
