I've been shooting Ace Standards since 2004. In that time I've taken an elk, a 200# boar hog, a bull moose, over a dozen whitetails and a bunch of small game. Never even a hint of a problem with any broadheads.
Not only are they pretty much bomb proof, they mount true without having to fight them, they sharpen easily and hold an excellent edge.
To be honest, I'd put the 160-grain Ace Standard up against anything in that weight range for overall quality and durability. And the price is great too -- about $20 for six.
