Yes, it's built up for most of what I build too.

I never really worried about grain (and density) until I built a Bubble Dancer RES glider and realised how much difference selecting the right piece of wood for the job makes if you're not overbuilding. If you are overbuilding you can can get away with anything as long as it's the right shape. Sometimes the piece of wood you need is buried deep in the sheet in your hand and is not necessarily aligned with the edges.
