Any of the Morrell' s will do the job and last longer than most other targets.
You might have to replace the actual bag every year or so but they dont cost that much.

If you want to shoot into a Mckenzie target then make sure you use plenty of soap on the arrows or get easy pull points it really helps pulling them back out.

As for the block they are good as long as you dont go shooting a lot of broad heads into them. The arrows are not that hard to pull from them either but they dont last as long as the Morrells using FP' s either.
