Nice pine - looks very happy with all that candle growth. I think with the earlier than normal warm weather, my pines (JBPs, Ponderosas, white) are a few weeks ahead of where they normally are in the growing season, as I've got lots of long candles on my JBPs and white pines, and my ponderosas are going nuts with new growth as well.
I think you're right about the issues you would face about turning this tree into a semi-cascade. It's too bad that long branch isn't higher up on the trunk. But otherwise, I think it looks nice with where you are taking the tree now.
