Congrats on your fish they are huge! Why do you harvest the bass over 14 inches? If it were me I'd harvest a slot of 10-12ish inches. I think, as far as CNBG go, keep harvesting the slot you are and you can get away with taking out 5-10 giants. If you want just let them grow till they start breaking your rods!
For the most part the handful that are deep hooked will be plenty harvest. Just my 2 cents.
