My elderly Kodak Duraflex development trays, originally my father's, are ready to be retired. I'm looking at several options and found the Cescolite dimple-bottom trays interesting. They are more expensive than the Cescolite's flat-bottom trays. Are the dimple-bottom versions intended to prevent negatives from sticking on the bottom during development? Would that be a concern for prints also? I don't tray develop my negatives and I haven't had prints stick to the bottom of the Kodak trays. Trying to understand if there is rationale to spend the extra shells on the dimples?

All feedback and comments are appreciated.
