Topic: Leaky Reeds

I am a new reed maker, I have been doing it less than a year.  Sometimes my reeds will seal all the way up the sides, but 70ish% of the time they don't seal more than halfway up, the bottom seals fine. I use gouged-shaped-folded cane from Roger Miller, and the warping seems entirely random.  I assume this is because of  warped cane, is there anything I can do to prevent it in the future?
