Hi, Man. Please don't play your cards so close to your chest or you'll either receive no answers, or non-helpful answers, or endless questions :-)

Take the time to explain what you are trying to do. Thanks.

If you want a heavier build up on the edges, preplate it with sulfamate nickel and follow immediately with the EN for corrosion resistance.
Play with the amps per sq ft to find the range that gives you the desired buildup.Years ago, we did this on copper heat sink fins where the customer wanted a bulbous leading edge buildup. We enhanced this by moving that portion of the rack closer to the anode.
