I've ridden the Hot Knife and while I liked it, I wouldn't consider it a bomber board. I found the flex was too soft for that. I would look at the Jaime Lynn or the Darker Series if you want a Lib Tech C3 for bombing. This assumes you don't need a true twin, as both of those boards are directional.
Salomon XLT comes to mind as a bomber board. Very fast base, and lightweight. I used to ride the predecessor (Salomon Special II) and liked that.
I like the specs on the Krypto and have read positive reviews on it, but I haven't ridden one.
