Personally, I use the Fatalis axe for it's high Blast value and element phial, so I would opt for Bombardier in that set. However, if you were using any other axe, including the Lightbreak Axe (with it's Power Phial), Attack Up L would probably serve you better. Of course, if you're also up against one of the few monsters not overly susceptible to blast, it's probably best to leave Bombardier behind as well.
I got super lucky with the talisman, Sharpness +6/Evasion +8 if I remember correctly. Put it with a mixed set with Empress Helm, Furious Rajang Chest, Rusted Kushala Arms, Furious Rajang Waist and Rathalos Legs. Comes with Honed Blade naturally and a bunch of points into other skills like Sharpness and Element Atk Up, so it's a good general purpose base set.
