Otherwise I've been using 180gsm and I think 220gsm- and they get sellotaped on the bases. Personally I like the higher gsm, but 180 is cheaper and is working fine.
Also, I'm so enthused that there are Firenewts and Giant Striders! I manually recoloured Lizardfolk and did a weird re-coloured mashup of Ostriches with one of the dinosaur heads to make mine a few months ago. If Firenewts come up again I'll definitely use these new ones and mine will become 'ellites' or something.
And Grippli! I can add them to my legion of Goblin/Toad mashups that I've been using for Grungs!
Another wonderful set, thanks again Rich!
