Any broadhead with at least a 7/8 inch cutting diameter will do the job for deer and hog in florida. 75 grain, 90 grain...100 grain...it all boils down to Kinetic Energy. Considder the weight of your arrow and the speed at which it travels. Pretty much any compound bow pulling 50# or more, shooting the arrows you mentioned tipped with a sharp broadhead will kill deer and hogs. If your arrows are flying as well as you say they are, I'd leave things as is. You seem to have plenty of power. Good Luck on your hunt!
