I'll have to check out my times tonight, if possible. It's been awhile since I've played it, but I wouldn't mind turning some laps!
Williams Grove has become one of my favorite tracks, honestly. I usually slide around the fence in turn one, but bring it down towards the bottom coming off of two. Turns three and four, I usually diamond them off. It just depends where I can get some consistent laps in, really. I don't know a lot about a set-up, so it's pretty much the stock set-up.
What a great game, really!
