10.8 pt playing card stock

I'm close to self-publishing a card game, where the cards will be held in people's hands & shuffled often.

I intend to use a card game manufacturer, who typically prints on 10.8 pt playing card stock.

I've seen people in this forum recommend using 300 gsm playing card stock, or 14-point C2S, for playing cards.

Is 10.8 pt playing card stock decent? (i.e. Is it comparable to 300 gsm playing card stock? Or is it twice as flimsy, or worse?)

Thanks in advance!
