Which of these detail/ upholstery tools is the most comfortable to use?

[Mikey P]

C would be the most similar to the old Prochem cast tool and the new Mytee

B is most like the popular PMF tools.

I'm interested in your opinion the angle of the vacuum chamber.

Imagine the tool as if it had a hide-A-hose installed.

B when the need arises for spotting, stairs

Although not listed, for me sappire. Light weight easy to manuever.
