I purchased and used the Sonic's last year. Simply put they shot great in my backyard and I was fortunate to take a 6 pt at 25 yards broadside that ran 40 yards and fell over dead after looking around for a couple of seconds. I will try to attach apic of the deer and if you zoom in on the pic you can see that the entrance hole was pretty big. The broadhead cut a perfect triangle going in and out. (I centered his lungs so he didn't go far.)

I am having trouble resizing pic so it will download, I will try to figure it out and post later. Sorry.
