I have a Portuguese floor corker now, but before that I used the same corker you have with No. 9 regular corks and No.9 Nomacorcs.I may have to try those. I am currently using #8 natural corks with my hand corker like this one: https://www.amazon.com/Home-Portugese-Double-Level-Corker/dp/B000FRWJNE/ Do they make #8 normacrocs? I'm not sure that I can use #9 corks with my hand corker.
