What a reflux column does is lots of re-distillations in the column to get a high ABV.
Home Distiller has a much better description than I could type of the differences between a pot still ~(which keeps flavour but does not produce such high ABV) and a reflux column
http://www.homedistiller.org/types.htm#refluxThere is a section on reflux design
http://www.homedistiller.org/refluxdesign.htmQuick answer - remove the packing and you will have fewer re-distillations and retain more taste but you will get a lower ABV.
Bit more detailed answer.
If you are getting an ABV of about 94% on a single run (without putting the wash back through the T500 again) then you have about 8 or 9 redistillations happening as the vapour moves up the column (the vapour condenses on the column packing, loses some heat, gains a bit more from vapours coming up the column and when it evaporates again increases in purity)
The fewer re-distillations the lower the ABV and the more taste.
The way I\'ve started to think about it (and this might not be right but makes sense to me) is that ethanol is ethanol. It\'s clear and it\'s flavourless. Your wash contains the flavours. If you have 94% ABV then you only have 6% flavour. If you have 50% ABV then you have 50% flavour.
So the lower the ABV you get out the more flavour, the higher the ABV you get out then the less flavour.
Does that make sense ?
Hope this helps.
