IMO if you do 99% of your practice shooting with field points a good Morrell bag target for shooting spots and a Morrell Bionic Buck for hunting practice just can't be beat.
They take so many shots it's unreal. When you wear out the cover you just replace and repack.
That and super easy arrow removal make practice a joy rather than a back wrenching experience.

I also keep a small portable block target just for tuning broadheads.
