quality balsa supplier
No problems in type or appearances of the balsa from Superior or Lone Star, but they are not too accurate on dimensions. The wood tends to be thinner than the fractional amount. Quarter inch stock comes up about 0.235' often. Thus it rattles around in slots. I now drive to Superior, and take the calipers along to check actual size before purchasing.
SIG is always more accurate, but they are a few cents higher too.
