@skinnylatte @vfrmedia wow building wheels spunds like super hard mode! I don't dare mess with spoke tension balancing 😅
The flats you get - where on the tube are the holes? Are they from sharp things that have got through the tyre, or are they near the valve, or are they pinch flats?
I had a bike that always got a hole by the valve - turned out the rim tape was badly placed and the edge of the valve hole cut into the tube. New rim tape, Marathon+ tyres, done. Never had a flat since.
