Favorite TrackPoint Cap?

Several years ago my team spent considerable energy inventing the perfect TrackPoint cap. What we learned from this exercise is that there is no such thing. Choice is what's important. People's fingers are as unique as the task they are trying to accomplish. We are interested, however, in which cap or other pointing device is gaining favor. Please take the poll at the left and be counted. 

Here are the TrackPoint cap images and names just to make this easier.
