Light inks on darks, 150/48 or 180/48 here. As with any ink you will probably need to use a UB or PFP on darks. The WFX athletic inks can be literally too thick to print, thinking of the grey underbase here as an example. These are the very rare cases where we will add about 1% Viscosity Buster (plasticizer) to the ink if clearing the ink is still an issue after stirring/warming/cycling some test prints to get it moving. Sharp and slightly stiffer blades, 70/90/70 is what we use.
We use Performance, not Top Score...well we have a can of Top Score red we got as a free samp and it's nice as a spot red. We did not see good results from either the Top Score base or White however. Others seem to do OK with it but we favor Performance.
Top Score was designed to eliminate some of that tack out of the back of the dryer for those with shorter outfeeds. We don't have an issue with it but we have an 8' outfeed with big fans on it. All the same, don't ever hot stack, let them cool as much as possible first and don't let them fall into the dryer catch and potentially fold the print onto itself.
