I dont see any 10". 2 of which you should look into. I would get 2 more 8". Maybe have a total of 100 3" tubes just to be safe.

Here in the states the distance to spectator rules are very specific. 70 feet per inch of gun--so 210 feet for a 3", 280 feet for a 4". etc. For that reason, and because of the lower cost of the shells, you will see a lot of 2 1/2" guns in use along with the 3" & 4" for smaller venues where space is an issue.
To answer your question, it really depends on what type of shows you plan on shooting & how things are done there. Just like Pyro, you can never have too much or too many!! Better to have them in the storage shed & not need them than to be short for a show & have to borrow or rent some.
Do you have 2.5" shells there in Sweden?
We also have 2" 1.3g shells here in the US but they are not that popular since they are so small & do not have much more composition in them than the 1.75" consumer [1.4g] shells.

The idea is not to take such large shootings to start with in Sweden it is not so very common for people to have fireworks shows in addition to New Year's Eve
Hi
and thanks for all the tips

in Sweden we keep at least 164ft to the audience it is 82ft per inch so a 3 inch is 246ft and a 4 "328ft but you are entitled to deduct 164ft per inch but less than 164ft to the audience but we have three different authorities say three different distance it is calculated per inch 32ft 49ft 82ft per inch, so no one knows again writing the whys
but ultimately it is always pyrotechnist who bear the ultimate responsibility if something goes wrong
