Planted a 11.5" merc. Stock coil not able to pick it up. The Cors Scout was able to pull it out. Its also a much quieter coil. Less chatter in SE. My prelimimary opinion is that its a definate winner with an inch, give or take, over the stock coil. A little heavier but i dont mind. Very solidly built. So i would highly recommend as of now but I dont have any real field time yet. I'll keep ya posted.
