Great question. No one knows the future, but here's our thoughts on this one:
Some slingshots may be more "hi tech" ( think https://simple-shot.com/axiomx ), but the simplest of slingshots can still be the most rewarding. Ever made your own from a tree fork? Right. They're fantastic!
So what the future holds? We think there's room for all of the styles that aren't gimmicks. Lasers and such? Nah. Until a laser actually can do what it's supposed to, there's no place for that.
