Brush or Bamboo?

Ive been making up some bamboo crappie hotels. Was wondering if anyone would want to share if they had found one material better than the other for attracting and holding fish? PVC? Brush??

Oak or other hardwoods. Bamboo (we call it cane) will only last a season or 2 at the most. Hardwood lasts for several years. I prefer to only do the job once.
