Question RE: Turbo Air still and cuts

[unifx26]

Sorry for another question haha, so I have the Turbo air still and 2x 25lt sugar washes (birdwatchers)

and I've read on the turbo air still instructions put 3lt of wash in, turn on for 2-2.5 hrs and collect 750-800ml and water down to 40% and run through the carbon filter.
but no where does it state to cut out heads/tails

but then it states if you do the first run and get the 750-800mls and do this 2-3 times then put that washx3 back in the still and do another run then it says to do a heads cut

does this sound correct? for 3lt of wash you get rougly 750mls of ethanol(40%)

I Guess what im really asking is if i only do 1 run will this taste like crap or should i do the runx3 and put that back in and do the cuts ( i want to try remove the heads, i've heard you can reduce a hang over, - dont know if this is true or not)
