I've got a soft spot for Stone Farm too, first place i ever went climbing.
There are some OK problems just follow your nose, you can do a quick walk from one side to the other and then get on what you like the look of. the Pinnacle you come to first has some good fingery pockety stuff. Most of it is boulder height / highballable just go for ones with an obvious tree root or that you've sussed out the top of, rather than realising you have to do an ultra scrittly mantle above a series of ledges. If you are on your own and time limited, less time driving means more time on the rock, and the approach is very short, assuming there is space in the car park.
