Beauty of Non Proportional button control is mostly cost. You still have proportional control via the foot pedal or machines slider (Depending on if the machine has a proportional two way feed). .......... I believe one major drawback is the lack of feeds for hydraulic attachments or a gripper, but IMHE it COULD be done with extra valves in the tilty and more buttons. .....
..... I am happy with control the foot pedal gives me. Would I now want to be without my tilt and rotate at the same time function.....NO!!! ...
Firstly... rory's comments ..
you don't need two way Prop for the button set up Rory ... single way prop is all I use.... the two way cetop3s in my VA-r do all the flow directing.

... the manifold is fed with prop. oil pressure and each solenoid, for each function, determines what happens when.
there is no lack of feed for attachments in mine ..
have a 4 way rotary coupling ... two galleries for my hitch and two galleries for my aux ports ... I have acquired a six way rotary, which could give me yet another pair of galleries, for either a second aux circuit or to double the flow to one pair of aux QCs. ... suitably plumbed/valved either/or could be achieved - I have another pair of spare buttons to run another cetop3 and it could be used as an individual circuit or in tandem, as the oil feed all comes from the same source

... a bit of trickery on the switching and could even make the one pair of buttons run both cetops, for tandem use ......
the lack of rotary and hence aux/QH couplings on the smaller units is purely down to their size prohibiting shoe horning a rotary into them -
quarts and pint pots - nothing more
as for Shauns comments ... I am blessed with a full size pedal in the 'Drema, so very fine control of flow is very easy, giving me equally fine control of the VA-r, from creep to pretty rapid motions

... just select what motion you want tilt and/or rotate and/or aux
.... what the pedal
doesn't give you is the ability to vary the speeds of each operation individually .... sadly, but you can't have it all without big bills to achieve it
...
however sharing oil flow does vary the speeds / way things happen and with practice you'd be surprised at just what you can achieve .... you can engage a second or third, motion after the first has been engaged and similarly disengage it to vary your requirements.
I am so used to selecting by button and using my left hoof to power mine, that I no longer have to think about it ... the couple of occasions I have been let loose on a prop. roller system, I found it very difficult to adapt and kept forgetting to let the rollers return to centre for off .... give me a day on one though and crack it I'm sure
.... pedal and buttons though is simple, with very little to '
go down ', leaving you scratching your head.
IMHDO, for most people, it's more than adequate to get you twisting and tilting, for a
LOT less than the '
all bells and whistles' system, which probably 90% of folks
really do not need
..... seems to me folks get hung up on having it, 'cos that's what they've been told is what they need ... uh uh !!
........ no way could I justify (to me) the cost of making it all fully prop., thumb controlled ... it just did not add up and would've added circa £5k to my roughly 1800 quid build cost, for mine
