Best rotary for black and grey

Does stroke even matter with no give machines? I mean, you can have 4mm of stroke and just hang out about 2.7 mm of needle and it seems to act the same as if all you had was 2.7 mm to begin with.

I think you got the idea wrong. Even if its 4 mm stroke it doesnt act like a 2.7 mm stroke even if you only use that much of the needle. The stroke goes like this 4mm is for colour packing. 3.5mm is for colour shading and bng. 2.5mm is for lining and bng. The stroke is how far the needle travels on the cam , bigger the travel more punch the needle will have thats why some people have give which takes a little off the punch its no different to coils bigger the throw more punch. Also a heavy cam will do the same as adding more to the punch or wieghts to a bar like the whip.

No offense but just about the only thing there I agree with is that a longer stroke and a heavier cam is going to create more velocity. The rest sounds like the old dime liner nickle shader mentality, which I have never agreed with.
