went for it today and let jasper off his lead, don't know if it was a one off but he was brilliant. Played catch abit then just followed us through the woods. If he went ahead too far we called him back and treated him, after a while he ran a bit ahead then turned to wait for us. Just hope he does this everytime. It made walking a far more enjoyable experience, so those of you still not taken the plunge, go for it.
