I got my Adrenaline a couple of weeks ago, and I have to say, I am a shade disappointed with mine. Could just be all of the great things I've heard about it thus far. Anyway mine is 15 lbs., drilled with the bomb at 45 degrees according to Ebonite's drill sheet. Drilling is designed to go a bit longer than a stacked leverage. Have used the Adrenaline in two different houses, two different leagues, and it doesn't seem to hook as much as I thought it might. Skates quite a bit for me on oil, and even seems to be outhooked by my Vortex 2 sanded, and Icon (I do have more surface on the Icon, though). The backend is smooth and predictable. Carry is average from what I have seen so far. I tried a gray scotch brite pad on it to get some more hook, but haven't thrown it yet with the gray pad. Don't want to go much more than that, because the ball is designed to get good length, with a powerful backend, and I don't want to to take that away from it. Apparently this is a great ball for a lot of people, but I haven't had that kind of success with it yet. Hopefully things will turn around with it, and if they do, I'll let you know.
