I find saddle bit, short shank, bent authors, apples and Rhodies are my favorite clinchers. It's all about leverage. The longer the lever the more force it exerts. The broad flat surface of the saddle spreads the weight and the bend brings the bowl closer in reducing the leverage exerted by its weight. Quarter bents seem to work best for me. You get the advantage of the bend without the cleaning difficulty of a sharply turned stem.
