Thunderhead pretty much looked like I just got it out of the package... I have to wonder if these broadheads "float" or "plane" a little bit. I was having issues earlier this fall with not very good groups out of the Exocet. I got it to the point where I felt confident I could make a humane shot at 30 yards or less. I put the dot just behind the front shoulder and ended up catching the last rib and the liver. Besides a straight down spine shot from a treestand, this deer died fast as could be, but it wasn't a double-lunger. Now that season is over, I'm going to spend some time with different combinations, etc. I must be cheap because a while back I bought about 10 packs of Thunderhead 100 replacement blades for about 25c each (spring closeout of a sporting good dept) I thought if I could keep from losing the original 6 heads, I could just replace blades for the next 10 years or so! I didget the broadheads that came with the package, I could try those I guess. I've also heard a lot of good things about Slick Tricks.
