Both are great targets, i have a Mckenzie in the yard that is 6 years old and still holds the arrows although they go in up to the fletch now. Biggest thing is keeping them out of weather even something as simple as a woodline with a thick canopy works, sun is killer. Otherwise you only get a year out of them. Definatley buy one where you can change the insert. Personally i would go glendel For a block target Rinehartt has zero competition. Ive had mine 3 years and it still looks brand new. Good luck!
