Any advice on aftermarket straps for Panerai? (besides Gunny straps, got tons already)

I've been a fan of trying different straps for all my Panerais; 90% of them I got from Gunny since 2010-ish. I haven't explored any other brands yet, especially the new-comers. do you guys have any advice?

I would prefer if they offer customization (dimensions and colors), just as how I usually get mine. Thanks for any advice!
