The thing about the Stratford track is even though it's probably the same width, due to the banking it seems a lot narrower, the corners are extremely sharp and you can't just cruise around the top if you get tired because it's just too steep to do that, you'll slip the whole way down. Overtaking and other stuff also needs to be done efficiently and with communication because you have less space. In short it's a lot less forgiving than HH. I wouldn't want to be on it with more than 20 other experienced riders, let alone inexperienced ones.
You so pro! xx
