Yep, and good luck in September if you decide to go for it!
One minor consideration is that you do get dinged for having a taut leash in both OB and Rally, and I'm pretty sure this rule is applied in all the major venues. If your leash is slightly longer, then you've got a little bit more slack.
It doesn't make a big difference because if your dog has a taut leash at 4' or 6', the dog's going to be seriously out of Heel position and you'll get dinged anyhow, even under a generous judge. But it can make a difference between 3' and 4' with a big dog, particularly as you're going around the curves on serpentines and Figure 8s.
