I always used Lone Star with great results but they are no more

I had received a recent order from National Balsa and was generally pleased, all the sheet wood was excellent (I specified contest balsa) but not all of the strip stock was that great.
I miss the days when a good hobby shop carried quality balsa & I could sort and pick the best...

I always review the plans and make a bill of materials for what I think is needed, and then double or triple the quantity. I order several airplanes worth at once so I end up with a good bit for stock, and always buy contest grade balsa sheeting as well as a lesser bit of standard balsa. There are a few places where harder/heavier sheeting is desired but the good stuff is so nice to work with and lighter airplanes fly better!
