Pang, I'm so sorry for my delayed reply, but it's a very busy time of year in my office. The key action was basically modern, so yes, well balanced as you put it. It was a nice ergonomic and economical horn. I ended up gifting it to a friend's son, but if I wanted a French horn without spending Selmer money I'd buy another in a heartbeat. I hope you had the chance to try the horn mentioned in your post.
