I've used both. The big ones for buff and the 130's for regular game on my smaller poundage bows. I just ordered more last night and some for a friend. I put a tanto point on all of them as well and they really hold up. I shot a hog this weekend quartering away hard with a 130 and my 57 lb Horne. I missed the spot where I was looking and hit the neck. The 130 Stos went into the neck, through one side of the skull and got almost a complete pass through on the other side of the skull. It was truly awesome so see the power. The Stos still looks new. BTW, this was a mature boar so his skull was pretty big! Incredible as it seems, the pig still went about 100 yards before piling up....they are tough.
