My predator has eaten my rhino block target in a really short amount of time. I am using g-5 strikers and grim reaper practice tips on it. I called the company and asked what gives, they told me it depends on the bow your using. A light bow will last longer, strong one will tear it up faster. That wasnt the impression they were giving off when i was researching targets. Of course they offered to sell me a new core for 50. I have read spyderwebs are good for practice tips, but i wont be using those. I have seen a few things on the blobs, but dont know how they are. Anyone own one? Any input would be appriciated.
