G1 for me as you're outwith the conventional hitting area. I think one thing that has to also be taken into consideration is cleft size, the larger the cleft, the lower the number of clefts you'll get from a tree. Therefore the willow vendors may grade more generously and charge a premium on top for the larger cleft. Regardless, matches what B3 call G1, and I personally quite like the looks! Hopefully it performs like a train for you!
