What would you suggest?

At the moment I am using the Winmau Snipers (pictured) with a No6 K-Flex Medium. As a rear-gripper I love that I don’t have to think about where my fingers go and it slots right into the groove every time.

Do you have any suggestions on similar style darts or any dart that would fit my style?

It doesn’t specifically have to be a scallop as I am open to exploring other options. Just as an American I don’t really have the ability to go to a shop and look so thought I’d take a shot and see what suggestions are out there.
