I play a fair bit of poker and often the tables use Copag 100% plastic cards. I find them really hard to do flourishes with especially spreads and fans, does anyone have any resources that talk about techniques for working with 100% plastic cards?
In my experience, 100% plastic cards have lent themselves to all sorts of flourishes really well (sometimes better than paper cards, though the resultant "paper cut" with them might be worse 😬).
Perhaps your issue is something else?
What spreads or fans are you trying out and what is the exact problem (gaps in spreads, cards slipping out of fans, etc)?
