I'd bet a dollar any bag targets that are hard to pull arrows out of do not contain the cotton stuffing, but more than likely has fiberglass or screen material inside. I have had the same bag target for 12 years(I am serious) with thousands of shots and its still better than most on the market. All I do is rotate back to front every 50 shots or so and replace the cover every couple years. My fatherinlaw keeps buying a new bag target every year or so cause he got a bargain. [&:] Best money spent is on a high quality bag target that contains cotton stuffing inside even if it costs more.

Back to the Maximas, no experience with them but a good chance you might have hit the arrow with another while shooting.
