I've used G5 broadheads for years. A couple years ago a buddy gave me some Swhacker mechanicals. "They fly just like field points and kill fast" he said. Well, I had to do some adjustment to get them to hit where I wanted, just like I do with a fixed broadhead. Though, they did fly a little closer to the field points.
We went to Florida for a hog hunt. I figured I'd used the Swhakers to try them out. The few hogs I got, There was a bigger hole, the hogs only ran an average of 40 yards, which is less than the G5's I normally use. I was pleasantly surprised by the blood trail, which was thick and easy to track through the palmettos. I've been a fan ever since, but still use the G5's for deer. The damage to the mechanicals was a turnoff. Unusable after hitting a hog or a tree, but did their job well and no failures.
