"He who marches out of step hears another drum." ~ Ken Kesey
we have 2 flashes on our 10 color, but rarely use the second one, however when we need it, it's super handy. We have our main flash in head 3, a lot of the times we lay down a color before the white, flash, and use always use a smoother screen on head 4...works rather well. I like flashes on stands, no in head flashes for us...I guess you are saying you loose 4 heads due to one being a flash and the other a cooling station?
We use the second flash all the time for 5+ color jobs that have stubborn inks that don't print wow worth a damn. I wish we used a mixing system and all of our inks were engineered to print wow but we don't. Most of our work is 4-5 colors, bold artwork, on darks with lots of ink area so having the second flash to hit 2-3 open areas of ink before we put a few more colors on works wonders for production flow.
Spot on with what Alan said with our 9 Color DB. Usually roll a tabasco flash into head number 6. Alan, I found a little trick for those stuburn inks that don't like to WOW and stay down. Wiflex fashion soft base. It looks and has the consistency of their curable reducer, around the same price per gal. Use about 2-5% in your wow inks and it keeps it from sticking to the screens, at that mix ratio doesn't seem to affect the opacity either or effect the finish of the inks. So far I've tried it in wilflex inks, and Union Maxopaque royal and scarlet red. Makes them a nice high opacity wet on wet able ink. Second flash, "on a movable stand", is a serious helper. I want to get into a 12-16 co machine next to have at least 3 flashes.

I tried it numerous times thinking it would help but the inks I added it to were terrible at building up so maybe there was nothing that could help those inks. My additive of choice these days is halftone/process base. Depending on who you buy it from it's either halftone base or process base. We use it for anything that needs cut, softened, extended, lengthen body, shorten body, you name it. I've tried many different bases and reducers and they all have done what I needed for the most part but this halftone base is all we have in the shop now.
