Try capturing the first one to cut down on time for the second one. Try at the 9 minute mark to capture it, bring a flash bomb if you need the time to lay the trap. Otherwise Felyne Heroics with said bow and armor and stay on YOUR left his RIGHT much easier to dodge his attacks if you stick to his right. I always Bring 3 pitfall traps and unleash everything Ive got on him and I havent had a problem killing him before the 10 minute mark.
