I shot a few into my block and they tore the crap out of it. Big chunks of it came out and the arrow was sticking out about 7" on the back side. It was a new block. They seem to go in good. Might be a wicked tip.
To me I would be trying to figure out why chunks are coming out the back side. In my frame of view that means there is some sort of adverse friction somewhere I would want to eliminate.
Of course I am not a big fan of right angle trailing edges, super thick blades, two blade heads or single bevels. But I do agree with Jonathan_S...I'd chose those over a Toxic any day of the week and twice on Sunday!
Also, they are manufactured in Oregon. If the business owners aren't a bunch of tools I always like to support NW companies! Might be a good option for someone wanting near Rage cutting diameter with a more durable construction. Price looks pretty darn good too!
