Rick, FOC stands for "Front of Center", or how much weight in percentage is positioned in front of the balance point of the arrow.
We'll need a couple things to calculate it -
1) Total Tip weight (or 260+100insert = 360gr)
2) The gpi of your arrows
3) the total weight of the rear of your arrows (weight of feathers, nock, and any adapters)
4) The total length of your arrow (carbon edge to carbon edge prefered, unless they were cut to nock center)
This should be enough for us to get you an idea.
I can tell you right now though, with that much weight out front, you'll be over 15%FOC easily. Those AD Trads are heavy arrows though, so that won't help your overall FOC.
