I'm still totally new to DHS....but i can tell you that I have DHS Hurricane NEO 3 39degree black on both of my viscaria. I used a water based glue (not DHS #15, it was free chalk) to apply the rubber straight out of the package to my first blade. I played with this blade for two weeks.
Then I took the rubber off, and I applied 2 layers of seamoon (first layer, then wait 12 hours, then the second layer, then waited 27 hours, then 2 layers of DHS 15 on the rubber). The rubber expanded to be several MM off the edge of the paddle (it was cut perfectly to the edge of the paddle before). The boosting process also produced a nice dome effect on the rubber. I waited 27 hours for the second layer to dry...and the doming effect was reduced a little bit but it was still there when i actually glued the rubber on to my blade.
Results: faster, spinnier, and more catapult effect than before. still lots of control in the short game. the gears were still there to say the least. i'll try and do one more layer of booster in about 6-8 weeks depending on the feeling.
My second blade still has the unboosted DHS on it. I haven't really used it much....
