This is a good idea: only let juniors skate at a senior nationals when it's the season before they can do so internationally, but no earlier. It's not a new idea, it's how the Russians do it (and I'm thinking of all this quite apart from discussions what the age limit internationally should be). I mean, last year was even more frustrating as Alysa couldn't even be assigned to JR worlds, but at least she could go to the JGP's the season immediately after - so in the same year. Sorry, not up to me, but I liked SnowWhites post on this.
