I have about 100 beatup 44/375's from years past that I use for bp, and only 2 52/300's worthy of bp status as we just switched to this ball. Question is, would the older 44/375's be considered safe to use for my J3A, or are they still harder than the newer 52/300? I want to get out this weekend and give the J3A a true test against my OG Ext and get used to swinging it as well. I just hate the idea of hitting 2 balls then going to retrieve them every time.
