Hey Kenny.... if you put that stuff in the core keep it as close to the back as possible and use real thin veneers, and really thin glass to get the most benifit.
and if it's in the core i wouldn't drop the stack height much at all, if any... or you'll end up light. Uni is pretty much useless in a RC under veneers bro.... a black racing stripe is what you get...
now you start playing with the Matrix carbon, and it's a different story...... STABILITY!
