I just brought back 3000 bf of syp.cca treat at .12 bf any amount.It took a long time to find this place but they will work with you and I can leave a load there is long as I want so I dint make special trips(about 50mi.) and it looses a lot of weight.He says a load will double in weight out of the tube.I prefer cca. to others and theres nothing wrong with it.I probably wouldn't make a picnic table out of it .
