Saxman, is that grape macro still alive? I had some come out of my LR and when I pruned it, it all died.
We had that racemosa in a few of our setups for many years, but I decided to go a different direction from the grape at the time. I kinda wish I still had some of it now, tho.
IME, if you "overprune" racemosa, it can p!ss it off a bit, and it will sometimes go "shocky" on you, but it generally bounces back since it's such a fast grower.
