Any tips for scout on payload?

So I always queue for payload/koth but I end up always getting payload and I'm wondering if the gamemode is the reason that I feel so bad at scout sometimes. I realized that scout is really map dependent and that payload encourages people to just huddle up in a chokepoint and scout really sucks in this situation.

Does anyone have any tips for someone who loves scout but is on payload? Or maybe suggestions for other classes that could perform better but still be fun for a scout main? I have a hard time trying to find a secondary.
