The only thing I can tell you is it depends upon you. Me personally i'd sell off one of my bd weapons, actually I did do that with my nq2 prizes.. So I could train, sense my pet's pretty small.
Although if your pet is pretty decent in size that you think you could get where you want to in fighting and be satisfied, then i'd suggest keeping the weapons and continue on fighting, making np on the side. Or you could also sell to get a multiple use big stick, like the SoS. I hope this helps a bit, it's just how I would do things if I had that sorta lineup
