I have 2 girls around the 1200 gram mark, they’ve definitely outgrown their little 9” x 6” Medium basic hides, and the XLs or something comparable are like $30 and up. I took a page out of Jason’s book (Morph Mixology) and hit up my local Dollar Tree for a couple hide upgrades. $2 and one deep razor blade slice later (My master craftsmanship skills at work 
)…not bad.
I think I like the rectangular one better I’ll probably stick with those from now on.
