Fellow Pellet Guys-
I've been lurking for years and finally have something to contribute. I've been getting back into jerky-making with my Yoder YS640. I was using what I considered traditional racks. However, I was always having to rotate them due to uneven air flow. I purchased some new ones from Cabela's and I have to say I am quite impressed. They have foldable legs that stand 2" tall and allowed for great smoke circulation. I was really impressed as the pieces smoked evenly with no rotation. As an added bonus the Yoder's shape allowed me to fit six racks.
Hope this helps someone.
