Absolutely agree Brian ref marathon not a sprint. I want this tree to grow strong and healthy and my natural inclination is to agree with you. I don’t know what the scientific / horticultural difference is for a tree in a lava / pumice / akadama mix as opposed to a tree in a well fertilised coarse grit mix? I must admit, I don’t understand things like optimal oxygen exchange and cation exchange, etc. I am using the LPA mix as that is what I believe is the best mix? So don’t know whether a repot or a trunk bend this year is best
