I was in your position with roaches... And my family was against me bringing them in. So here is what I am going to say.... Honestly they are better then crickets. Crickets jump and smell awful even when cleaning all the time. What I love about feeding dubia... They really have no smell and they are super easy to clean. I simply tilt their little bin and use tongs to direct them into a clean bin. Most do not climb plastic either, they do not jump, most do not even fly. I am now at a point where I have fed them since March doing away with all crickets. I do not mind them at all now. However I hate the adults... They give me the creeps still but to avoid this I just do not breed my own. You can order exactly what you need so you don't have to breed. I buy mine from our site sponsor dubia roaches. I have been totally satisfied with what I get from them. I believe with you being in FL that you can buy discoid roaches which I have been told chams seem to enjoy more...
Ok so now the benefits for your girl. Roaches gut load really really well due to having a long digestive tract so you are passing on so much nutrients to her. You can cup feed these as well. I have found that Beman seems to be much more content eating his roaches like they fill him up more then when I fed crickets. I also like that roaches do not carry parasites, so much less risk.
I think it is funny you like the BSFL... Omg the first order I got I freaked out totally. I literally could not stand to look at them. I took them straight to my local pet store and gave them to them lol. But I use these as a staple as well now. Some people gutload these and some do not. I do not happen to gutload these. I could never get it right. I do use these for when I want to dust with pollen. Since you need to rinse the fiber they live in off I do that then dump them into my pollen tupperwear. Since they are wet from cleaning the pollen sticks perfectly. Pollen is really hard to get to stick to other stuff IMO.
I feed silkworms as well. Not so much as a staple though. Beman gets hooked on these really easily and will then refuse all other feeders. But yes they absolutely can be used as a staple. This is the best thread I have seen on raising silks

It will really show you what you would be getting into. But you can order these from Morifeeders another site sponsor as babies and not raise your own. Buy them smaller then you will have them the right sizes longer.
So the key is balance in what your feeding... Offering a variety. Right now I am feeding silks, dubia, BSFL, BSF, and Blue Bottle flies. I feed 2 silks, 2 medium dubia, 3 BSFL every other day and then he has the BSF and Blue Bottle Flies that hatch out in his cage in a gum container. Some days he gets 1 or 2 others I have like 10 flying in there lol. Now I have a male so for me I do not have to limit food intake like you will with your female. Carefully monitoring her intake and heat since it is directly linked to her laying a smaller clutch of eggs.
Hope that helps
