You've won a lot of awards regionally, haven't you? Not competing at world level doesn't necessarily mean you're a novice...you're skilled enough to be in Journeyman. I went straight into Journeyman the first time I entered at CC because enough regional Best in Class awards means I'm sure as hell not a Novice.
But yeah, email the masq. directors and ask them. they have the final word on it, anyway.
