I would shoot them thill they were lost or broken, then, use point weight to get it up. With out going to extremes, 100g brass inserts will put you at the weight you are used to right now. Why not try 6 each as we just described? The next time you get a hog, or scrub jul, or wild camel, have a first hand look at what your set up is capable of doing.
With as much arrow as you are using it won't matter much
Although, I shot 490g from my 75#'er, with a F/F string. I now use about 550g total on my 63#er. Good all around set-up. I draw 29.5" target style, 26" Hill style. Most animals don't wait for me to get to 29.5" ha ha.
