I have a OneWay Stronghold chuck that I use for bowl turning. I also have
the OneWay Jumbo Jaws. I have been doing a lot of smaller bowls lately and
find the Jumbo Jaws very handy for finishing the bottom. Consequently, I
spend a lot of time switching back and forth between the jumbo jaws and the
regular jaws. Does anyone know if any of the less expensive chucks will
directly take the OneWay jumbo jaws so that I wouldn't have to do quite as
much jaw manipulation?

This isn't what you asked, but the Nova allows you to put the 50MM
jaws on top of the Cole jaws.
You can also use a screw point with certain jaws.
