Here is a Slick Trick "Viper trick" version 125 grain success from this year.
It looks to me like the wide blade makes a wider then 1-1/16" slice going in. This was a great hole from a fixed blade head. Actually the 1-1/16" blade is on the small side of fixed blades too.
Best of all is that they exit every time even from my 63lb 28.5" draw. Nothing fancy or really fast. An old SWBXT shooting 440 grain arrows at 265fps.
