Ego is very similar to the Track Threat, X-Factor, and Inferno. It gives the look of a strong pearl with a strong roll in the midlanes and backend continuation. Like the above mentioned balls, the angle of the backend can be fine tuned according to what type of drilling that you use. It's columbia's benchmark pearl I guess you would say. It's a bit more ball than the Ti Messenger Pearls and a little less than the Wicked B/R/T but it is more angular than the Wow Pearl in the Flipside line of balls.
Hope that helps.
