My current set up for weddings is 5D, 1D MK IIN, 17-40, 24-70, 135f/2, and 200 f/2.8. The recent acquisition of the 1DN has made me want to upgrade my 5D to a 1Ds MK II. Do you think it is best to keep my set up the way it is or would it make sense to sell the 5D and 17-40 to get the 1Ds MK II? I rarely ever use the 17-40 even though I love the lens.
