You've brought up another good point. The only lisse exotic being offered is in gator (no croc, which is only being offered in Matte). I have a few gator Kelly pochettes and Medor in gator, but my birkins are croc. It feels like the croc skin is also a bit thicker/sturdier?!? but I'm not sure if this is by virtue of my gator items being smaller or is croc more sturdy. Does anyone have any info if gator birkins are thinner than croc?From my understanding, ostrich is slowly trickling back into the market, so availability might be less of a problem compared to recent year shortages. Having said that I am okay with gator on small items but for bigger items I prefer the scales of croc. So I'd choose ostrich. Plus handles on dark blue ostrich will fare much better than a light color. Good luck deciding on this wonderful dilemma!
