Here is the reason for the question.I have bear trip booked this spring in Canada.I have shot the 145 eclipse head for years even before they where called eclipse.I have had some great and not so great blood trails.
I have hunted with the Simmonns tree shark the last couple years with 4 whitetails shot and great blood trails on all 4.(Huge blood trails)
It seems that a lot of people see the need for a multi blade head on bear.I want to settle this part of my equipment if you know what I mean.I can not imagine a bears hair and fat closing the hole behind a simmons tree shark.I like blood on the ground and lots of it.
