Vince,
I went from an old Delta 12" "school lathe" to a Oneway 1640 about 4 years ago and as most of my work begins with a bowl, have been turning outboard about 80% if the time. It really saves my back and vision to be able to stand straight and move around the end of the short bed. It is true that it is what I have become comfortable with. I may begin by turning the outside of the piece inboard between centers if the blank is much out of balance and shift the piece to the outboard to turn the interior. I also have a tailstock riser so that I can use the tail stock outboard if it is needed. The 1640 essentially gives me two lathes: a 16" spindle lathe and 24" bowl lathe. Coring is is limited to inboard as there is not enough outboard bed to accommodate chuck, blank, coring base and knife, and tail stock.
In the short of it, my aged and abused back appreciates it most of all.
I use chucks almost exclusively.
