That's the big benefit to me. With the "standard" mandrels that screw into the #2 morse tapers, it seemed that I was always having to add just the right number of spacer bushings to fill the "empty space" of the long mandrel, especially when turning a single blank pen like the Sierra or Polaris/Atlas.
Now, even when turning two part pens, I always use the Bealle chuck. I usually turn each half individually to give that wobble free feel then mount both halves when applying the finish and final sanding.
I'm never in a hurry so the extra 4.75684 seconds it takes to loosen the collet and add the second blank really isn't a bother. [

Another benefit is when doing closed end pens. When working on the end of the blank, the rod is securely held by the collet, no chance of coming loose as the #2 morse taper can do.
