Been happy with mine on deer - but I'm not sure I'd use them on something dense (like hogs) or big (like elk) at the poundage I pull (60). They fly very well.

BTW their "100 grain" heads weigh closer to 110. I don't mind, however, because they fly almost the same as my 125 FPs (which are heavier but have less wind resistance, so things even out).

This subject comes up fairly often, so you might also want to use the search function on this and other sites.
