To Sell or Not to Sell?

I've been doing a lot of thinking recently. I love my spider girl, Charlotte, but I've come to realize that there are better spiders out there (at least are more of what I personally love in spiders). Because I want to breed high quality spiders, should I sell my 600g girl to pay for a younger, better spinner (because most people know I secretly love pinstripes)?

Or...Do I keep her in my rack because I've put in a good bit of time and money to get her up to those 600g (she was roughly 70 when I got her)? I mean, she's not a terrible spider. I just happen to prefer mine to be more"yellow", have a more broken, reduced pattern, high white sides and no striping on the neck. This is a tough one for me!

I also have a couple of corn snakes I'm considering letting go. I have a 140g snow motley female and a 70g Anery Motley het Amel male that I'm considering selling as a pair. I have sentimental value with the snow motley because she was the first corn snake to survive in my care (no, I'm not a horrible snake owner...the others died for reasons out of my control). I've had her for a year and a half and I've raised her since she was a 15g hatchling. The male I bought specifically for her so I could produce some anery motleys and snow motleys.

I know that corn snakes won't earn me any money and I have a bloodred/hypo lavender breeding pair that I'm more interested in from a project standpoint. So, should I sell the pair or keep them? Decisions, decisions, decisions.

Does anyone else ever struggle with decisions like these?
