Thanks for the continued responses!
As a matter of fact, some years ago I did omit saying "to" and "for" whenever possible. Then, a few years back, I mentioned this technique to a controller in an off duty conversation. He cautioned me not to modify clearances in my readback, but do it verbatim. Since I could not produce a reference document to support my technique, I adopted his stance. I suppose that was bad advice! I will revert to my old way of omitting to's and for's! Thanks again!
