I thought this may help out others who might need help wicking the profile unity.
It is my favourite rta and also the easiest to build and wick. The way is vapes reminds me of a mesh pro or falcon but a bit more flavour. Perfect at 65 Watts, it is on the cooler side but there's no ramp up, just like a mesh sub tank.
First I use 3/4 of a cotton bacon or similar cotton strip.

I then cut the cotton flush against the base.

Then cut the wick from the bottom at an angle so the top of the cut is in line with the wick slots.

Stuff the bottom of the wick into the wick slots and then saturate the cotton and you should be left with something like this.

Now you should never get any leaking even when filling it to the brim.
Hope this helps out others who are struggling.
