Mikuni round main jet size

After reading Factory Pro's CV carb tuning guide, I'd like to try going up another main jet size. When I go to BikeBandit's website, I see they have options for large round main jets, small round main jets, and round main jets. Which is the correct size, or doesn't it matter?

Thanks.

Not sure what carbs those are for. Stick with FZR600 specific Factory Pro or DynoJet jets. You can usually order them direct from their respective websites.

After going on Factory Pro's website (how can such a well known company have such a headache-inducing website? But I digress...), I found this page about ordering individual jets. It gives the "small, round, slotted" jet diameter to be 6mm. I just measured the stock jet diameter to also be 6mm, so I guess the FZR600 uses the small round size.

The jets in the Factory Pro kits are manufactured by Mikuni, so they should be the same as the ones on BikeBandit.
