Darrin,
I started with boring bars and ended up becoming a turning terrorist - explosions, fragmentations, missles everywhere.
I bought Randy Privetts Articulated Arm because the price was very reasonable. After using it for some time, and making some nice hollow forms, I've begun to try my hand at free hand hollowing again (using Ellsworth tools) now that I've got a better idea how hollowing works. Still a struggle but a lot of fun.

I recently tried to hollow a small piece of old olive wood free hand. Gave up as the tools beat me up too much. Will finish it on the arm.
While in good shape for my age, I don't have the upper body strength to fight thru dense woods that you spring chickens can zip through.
YMMV,
Burt
