As someone who formerly did ops at Leading Edge I'm obviously biased. But I'd suggest that as the school was busy this is a healthy indicator. Anyway, pop in anytime and speak to John McGeough on the ops desk in the shop. He's in Friday-Monday this week, but he will make time for you if you go in and speak to him. If you pop in any other time one of the instructors will be delighted to talk to you. I will pass on some contact details to you in a pm.
One wee thing I'd like to add is that if you are looking for somewhere with Katanas as far as I'm aware there are no places locally that use them. I know that older Cessna 152's, PA28's and PA38's all the aforementioned schools may not look as modern as the Katana. But they are tried, tested and proven over many years of flight instruction as great platforms to learn on.
Anyway, good luck whatever and wherever you end up flying.
Paul.
