I agree with Ted on the Longleaf density. Slash has come a long way in terms of rust resistance and overall seedling quality. It has been genetically modified but not near as much as lob. Remember with Slash that silviculture comes before profit. When it is time to thin Slash you need to prioritize getting it done because you are typically dealing with a site condition where you have smaller windows (weather /markets) to be successful in thinning operations. Slash has a tendency to stagnate, so you need to keep your stand growing by timely thinnings. I'm on the fence in terms of planting density with Lob. I haven't planted less than 545 per acre yet, but current markets in some areas, seedling genetics and cost, and especially downward pressure on rotation lengths, have me thinking that it might be worth considering in some areas.
