Gol= boring the back cut, generally with a saw that is to small or bar that is too short. Not necessarily looked down on, just a waste of time on most timber, the game of logging mentality is that all trees need bored period, they don't, there are other more productive methods, some are safer, some are easier to steer with.
Ms P, Alders are a little more brittle when frozen, but are lighter on account of not having the sap up, its a trade off. I reality they are just brittle and chair prone all the damn time. Veneer buyers are going nucking futs over them right now, anything over 12" and straight paying close to ceder prices.
