i wouldnt go with either a 100 of 125 grain i would go with like a 85 grain broadhead. i mean 210 fps is enough to kill a deer but IMO its cutting it close so i would go with a 85 grain and would maybe get some more fps.
An 85 grain would be a good choice also, but we cannot give you any more advice without knowing your setup.
