hello ash
welcome to the forum and congratulations on passing the test..i dont normally carry pillions, the few times i did it i was very concious of keeping everything smooth and predictable and my pillion was so good if it hadnt been for the loss of a bit acceleration i wouldnt have known he was there, i would say when you feel confident enough to do it then you will be ready,just take things nice and easy and everything will be fine
