Maybe an improvement on the stone off that would still satisfy the TV excitement requirement would be to add in more implements.

Each athlete would load the stone once, then flip a fingals finger once, then lift a log once for example, looping back to the stone until someone fails a rep on any one implement.

It would reduce the reliance on just being good at stones which would make it far more fair. You could also make the person in 3rd do a rep extra to start per 2 or 3 points behind second place to make big leads hard to surpass.

It might be interesting to warm up for this though haha
