Would I be better off with my New Balance 760s or Nike Zoom Rival 5s for TJ and LJ?

I have these two shoes, the 760s for training and Nikes for competition. I'm a 200/400m runner and did long jump last year with my Nikes but I'm looking to jump more seriously this season, going into the triple jump also. I don't really want to buy jumping shoes, but I guess I will if i have to. For now, which of my shoes should I use for jumping?
