over the years I have slowly replaced most of my traps with jacks.. i usually get 2 new one's per year. I have 10 now so i'm set for the time being. I also have some heritage and indian hill's, both good traps. And polars too which have their time and place (trout, thin ice, shallow, etc). Of all that, I will say the jacks are the best investment. If you take care of them, they will literally last forever. Good luck with it and enjoy!
