Main point is to adjust your water speed/volume/pressure whatever until the output water from your coil is hot to the touch but no vapour escaping.
With the 2" bok, run it slow for a start, 3 or 4 drops per second until you get out of the foreshots, increase slightly to get through the heads.
Once at that point, do not lower the heat input but you can increase the product take-off rate to maintain a head or upper column temp of around 79C max., as the temp rises, slow the product take-off down, if it drops, open the tap a little. On a 2" bok you should be able to run most of the hearts off at a fine or broken stream.
By the end of the run you will not be able to close the tap any slower to keep the temp below 80C by which time you will be at the tails and you may just as well open everything up and strip the rest as fast and for as long as you want.
This method will result in a very slight loss of %abv, no perceivable taste difference but a lot less time sitting on your arse.
Cheers.
