Don't have any pix, but I've been using Abowyer single bevels for a few years now, not exclusively, but I have killed several deer with them.
In two cases, they were good double lung hits, and the critters died within 100 yards or less. In the third, it was a liver, lung hit. Of course, they would have died just as quickly with double bevel heads with those hits. Blood trails were adequate, but to my eye not greater than a double bevel two blade would have produced.
That being said, I'll be shooting Abowyer brown bears on my elk arrows next fall. Because the cutting edge angle is most acute with single bevel heads, it's possible to get them sharper than double bevel heads.
I'm not shooting single bevel heads for their bone splitting capabilities, though I may appreciate that someday. I shoot them because i can get them extremely sharp.
