I actually run 8 frames in a 10 frame with 2 follower boards all pushed tight. Breaking them apart is never a issue. The bee's dont use the #1 & #10 frames anyway. They will store honey in them but they seldom get to them when in cluster. I started doing this one year when I ran short on drawn frames. With less then 10% dead outs out of 50 colonies I think they overwinter better with is air gap on 2 sides.
But I use 9 frames with 2 follower boards all pushed tight.Been use follower boards for the last 30 years or so.I'v owe use follower boards in the brood nets not in the honey supers.

Same here Jim. Only the brood nest but with 8 instead of 9. This leaves about 1/2 open on the outside. On occasion I get a colony the burs this space up but this almost never happens. I like the extra room when removing frames and the reduced weight of the hive body. I hate the way 10 frames get so tight that the first out and last back in gets ripped up.
