Makes sense. Even animals know when they're dinner selection is overly redundant. Though they may not cognitively approbate it like we do, they sure are aware.
A varied diet is the best diet. Pinkies are an okay addition, though I wouldn't go any bigger in terms of rodents. One a week is a sufficient treat. Larger, but not too large, insects should be provided as well. Large crickets, small roaches, baby hornworms, silkworms, occasional butterworms, and fresh fruits (raspberries have a good natural calcium amount).
As for giant mealworms, I would recommend normal mealies and/or superworms instead. Giant mealworms are just normal mealworms on steroids. Some people just don't like the sound of that. I can be quite the hypochondriac myself, lol, so if you can avoid them to be safer than sorry, why not?
