Congrats!! I love spiders (awesome name for her too, btw)

Well, from that feeding schedule it looks like he was alternating sizes and just using whatever he happened to have more of at the time. I would say that at 278 grams she's a bit too big for fuzzies, and I would either keep her on the hoppers for awhile (maybe move up to rat hoppers if you can find them) or you could probably even move her up to normal size mice. I'm a visual person myself, so it's harder to say without pictures, but whatever prey is about the same width as the largest part of her body would be fine
