I don't know much of woman's boards but I've recently been on a 2014 NS Raven ca 145 (the Lotus replacement) and Salomon Idol ca 149. Don't know what speed you're into... the straight line part of the test slope was short and rather crowded so I didn't go very fast, but I xan assure you that both are chatter free at 43mph. Considering that you're 1st year rider and already charge and jump, you seem to progress pretty fast. I'd say don't be afraid of "aggressive" woman's boards. Both, the Raven and Idol are among this category but ride very smooth, well dampened, easy to turn/edge to edge.
The Idol might be worth to have a closer look at, it's a hybrid camber that might feel more stable than a hybrid rocker if you want to charge.
