B/W/B primary spring, 14.5mm rollers, EPI purple secondary spring wrapped at 0/1 with a 47deg helix. As far as loading up your Supertips, you will have to do some more research on that one. I run Dalton DPYR adjustable weights with 94grams in them but the Supertips have a more aggressive angle so you will need less weight. I am sure someone can chime in on a starting point with those weights. Shad
