I use AD Trads with a 100grain brass insert, 100grain steel adapter, and a 190Grizzly which weighs around 175grains when sharp. That gives me a total of 375grains up front.
I can replace the 175grain Grizzly with a 160 field point and it still works well. I can also replace the Grizzly with a Tiger Claw small game head which weighs 145grains and it still works well. I can remove the machine screw and claw cap from the Tiger Claw which gives me an 85grain blunt. Onto this I press on a modified 100 grain Bludgeon that I've cut notches around the face which ends up weighing 90grains. Installed onto the Tiger Claw it weighs exactly 175grains which is the exact same weight as a sharp 190Grizzly. I use this for rabbits, stumping, and such. All combination fly well and are accurate enough for me to hit tennis balls with my 67pound longbow:)
Best,
