    My best advice would be to call Isky and talk to Rod. He is the man, if you give him your specs he will pick out a perfect cam for you. Me and my brother have been dealing with him for years, he is a great guy. I believe he is on Vacation next week, its worth the wait if you want the best cam for your combo.
