In reply to AAG353:
I know what you mean. I used to try and find low grade climbs on the tors when my kids were young and we were holidaying there, and found very little.
Granite climbing here tended to be bold, requiring good jamming technique, faith in friction and avoidance of lichen. It can be scary because there tends to be little in the way of good in cut holds - not good for beginners.
I haven't seen a current guide book, but I'd be surprised if there is much lower grade climbing.
