LF - absolutely right. However, for those wishing to practice on some cheaper material before putting their hands and tools to the Grade A or B culms - this stuff - or others from Wal Mart, Home Depot, etc - is excellent for practice. A couple bucks for a 8ft culm versus 40+ ..... easy going practice material.
But yes - if it's green ..... not too good for a couple years.
