I haven't shot either of the 2 heads you mentioned through mesh, but I have shot 2 different types through mesh (both were 0-ring or rubber-band type heads) and both of them opened up when they went through the ground blind mesh.

I actually found this out 3 years ago when I shot a turkey from the blind - amazingly even though the blades opened up, I still managed to hit the turkey at 35 yards (luck maybe?). I then tried out another type of head (can't remember the name) and it also opened up when shot through the mesh. I would recommend staying with fixed broadheads for shooting through this.
