Hiya Tom. Based on the fact that you cut from left to right free hand, method 2 would be indicated. I have seen Norm Abrahm cutting opposite to this with the explanation of less pull into the work. When using the fence as a guide is there a right or wrong way? This same question came up under cutting dado's and I suggested having the guide above the work and cutting left to right. My reasoning was your router is flipped and the cutter is rotating in the opposite direction compared to when it is table mounted. And table mounted routing is done from right to left.
