I personally think the benefits of having more JS outweighs the cost as long as you aren't getting up to the 18+ JS. In almost every offense the SF will be shooting a lot, and SFs take so many Jumpshots in neutral and outside offenses, I think it is important to have a decent amount of JS. Any lower than 15 at the top level in the USA would be a struggle I think. It is probably slightly different for top leagues such as yours though, so I can see why we have different perspectives.
