Hey guys,

I'm going to build a rack real soon and plan to use some 28 qt. and 41 qt. sterilite tubs. They'll both fit in the same rack because they are the same height. The only thing I'm not sure about is what size flexwatt to use for belly heat for these tubs. I'm going to put the tubs in long ways not sideways. My thoughts are to use a single row of 11" flexwatt in the back? What do you guys think is best?
