I have not used that machine. I like light machine for lining - and heavier for shading - but I really like all my machines to be setup really light because I use disposable tubes and grips.

Looks like i got the knockoffs Not bad machines tho from my limited knowledge, Bought a couple of hildebrant machines aswell & im less than impressed with the tinny sound they make,, looks like im up for a couple of rebuilds. I like the frames but the armature bars & springs have to go.
i just got a new pair of workhorse irons (SOBA designed) got a mini rusto, and a pilot shader. amazing machines, a lil better than the sharpz imho (atleast the new shaprz that is)
