Yes, Bob, every move to a larger neg tends to have this sucking action.
Yesterday I went into Cord Camera, as always every Sat. They've got a Mamiya RB67 ProS, 90C lens, 120 back, and prism(!) for $350. Had to turn on my anti-suction device. It was hard. Did end up getting an excellent Fujinon-W 125/5.6 for a mere $200. Rodenstock 135/4.5 FS. :)
