I actually misread his reply, I thought he was speaking of another brand with "black" in the name. Regardless, if you were to see the work that some of these folks put into making these wood baits, you'd understand the price. The time that goes into one of these baits blows my mind sometimes. Knowing the work and quality that goes into some of these squarebills, I've paid up to $50 for some of them. That's not to say you can't find a good balsa bait commercially produced that are cheaper, there are many out there.
That being said, I have too many cranks, both plastic and wood, that I call my favorites. However, when it comes to cranking through the laydowns, I don't believe one can dismiss the value of a crank bait that quickly rises/backs out upon making contact with the wood. That is one attribute where a wood (balsa) crank really dominates other baits.
