Welcome,
Catapult Carnage in YouTube hunts a lot with 8mm and I have seen him use many different types of band thickness trough out his videos also Catty Shack Hunter likes to hunt with 10mm lead if I can recall correctly and he likes shooting thick bands for his setup so you can search them up and see what you can find. Also it all comes to personal preference and elastic is a little wishy washy you just need to try several thickness with the ammo you decide to use since they can all work depending on the taper but some may give you an easier pull and the same speed that other thickness or even a faster speed since thin elastic retracts faster.
I started with the .7 went all the way to 1 and now I prefer shooting .45 full butterfly style with 9.5steel.
Hope I helped you at least some good luck in your quest.
