What would you like in a sample pack?

Hi Guys,
I'm getting interested in putting together sample packs for all kind of genres. I know there are a lot of those out there already but I'd like to bring more, which is why I thought I'd get in touch with producers like you guys to find out what sample packs lack as of today. What would you like to get your hands on when purchasing one of those?

Hopefully I can provide you with things you really need instead of an extra pile of kicks or hi hats!
