I presume you are referring to pressure relief holes.That is one of those issues which has been discussed many times on the KR Net and can easily be found by searching the archives. But, to answer your question, this is also a personal preference option. If you feel better having the relief holes then drill one in each chamber or through each vertical rib inside the spar as you build it. To our knowledge there has never been a spar "Explode" or delaminate due to pressure from altitude. I opted not to install them in my spar and I have not fallen out of the sky. YET!!!
