I've been keeping balls for 6 years and breeding for 4. I've never learned how to probe. I'm happy with my pooping skills. As long as your gentle there are no issues. When you really know what to look for you really dont even need the spurs or hemipenes to pop out you can Just look at the base and know. Probing has always kinda scared me I guess. But I've never been wrong with popping. Work on popping a little more.
