I think the toxics are what you get when you have something people spend a lot of money on (broadheads) and that has long been already perfected.
I think a broadhead should offer just the right mixture of penetration and cutting surface but that combination was discover long ago with simple 3-4 blade heads.
Now it seems more about reinventing the wheel to make money.
Slick trick,Muzzy,thunderhead,G5 montec etc........they already got it right and are hard to compete with on the market so companies have to come up with heads like the toxic.
