Narrative:

Descending VFR into ptk working with detroit approach. ATC advised me to stop my descent at 6500 ft due to IFR traffic at 9:30-10 O'clock position. I advised I was going to continue descending into ptk and ATC pointed out traffic again. I responded with my call sign, I had the DC9 in sight. ATC advised me again and I told him I had him in sight. I was a little higher than the DC9. I knew I was going to miss the aircraft below or behind. His TCASII went off and made him climb. I always had visual with him. ATC never moved the DC9.
