I prefer a one-touch, myself. But, again, the f2.8 suits your style. All joking aside, the 80-200/f2.8 is an excellent workhorse lens for motorsport photography - it even works pretty well with a 1.4x TC for those occasions where you want the extra length. The drawbacks, of course, are obvious - it's heavy, and it's not cheap.
