I agree with this ... but ... you need balanced cutters for 15k and if you are working with people who are not the sharpest tacks in the box it might be wise to compromise on 10k. With 15k it is possible to run the risk of toasting your spindle with an unbalanced tool but this is not likely with 10k.
