For what it's worth, I don't think there's anything wrong with using the convenience diets -- after all folks, it's not like she's feeding them oreos and gummy worms -- but it seems to me that everything in the cricket meal is contained within the leopard dust, and since you're not feeding leopard geckos, I wouldn't buy the leopard dust. The most valuable parts of the feed should be passed along to the predator. The two problems I have here are that I'm not a zoologist or animal nutritionist and I don't know what an optimum diet is for crickets, nor do I know optimum vitamin and mineral needs for cresties versus leos.

My best guess would be to use the cricket diet but vary it a bit with a chunk of carrot or apple or potato for water and fresh, unprocessed food, and skip the dust in favor of the simpler plain calcium with D3 and the herptavite or similar (or use the dust in place of the herptavite).
