Paint question

the dilemma in a nutshell. I’ve found a new range of paints that I’m very tempted to switch to, however it was only in June that I’d spent $400 on buying cans of the current version. However the new types are what I know a major UK competitor are very successfully using and they seem much more modern/trendy. 

I can offer both, but potentially giving too much choice. 
If I switched, would lose all glossy colours.

this is the much more limited palette the competitor shows, but in their listings they make it clear customers can request others.
