In reply to olliecamel:
In terms of purely top roping areas, all of Southern Sandstone is top rope only due to the fragility of the rock not supporting lead climbing. Whether you find the climbing there appealing is another question, I personally am not a big fan but some like it well enough.
I would recommend however that you look into a basic trad introduction, specifically how to make trad anchors. This would open up most single pitch trad crags, eg all of the eastern edges in the Peaks (Stanage, Burbage, Frogatt etc.) These all have accessible anchor points at the top so you could top rope without leading if so desired.
Having said that, I definitely second (no pun intended) the notion of finding someone to climb with so that you can second the route they've just lead. You'll get the most mileage and most freedom of routes this way, all whilst avoiding any leading falls. Many people are looking for someone who would belay and second whilst they lead, especially if you can climb hard routes as your logbook suggests, so you wouldn't be short of partners I suspect.
