Looking for the largest tip opening

[tseligas]

So i did my research and I discovered a variety of information.

Check out this link first for a clarinet tip opening comparison chart. https://www.google.com/url?sa=t&rct=j&q=...7431,d.dmg

Do you agree with me that this is probably the trick for greek music?
So check out the chart above and see that there are mouthpieces with up to 1.78mm opening vs the 5JB.

Any experiences? I would like to see how the extreme feels like!
