There's nothing wrong with having an ego, as long as it's kept in check and it's owner knows the appropiate times to use it.
Cesar, has it ever occurred to you that some DJs will do things differently because they choose to, not because they're not good enough? I handle the majority of the MC work for our company and I can hold my own against some of the best. Like Ducky said, we've been up against many a DJ like yourself and on most every occassion we've won.
For introductions, if you've ever worked on the production side of theater (which I have a few times), you'll know that what you say and how you say it are only a fraction of the overall success of an introduction.
And for the record Cesar, I find comments like, "Thats because you haven't been up against a DJ like me in your consultations." to be very insulting. You're not in my area, you've never seen me talk to a potential client, heck we've never even met. Until you move your business into every market in the country, work with the people in every market, I would appreciate it if you would keep quiet about other DJs and their skill levels/their business practices unless they specifically ask for feedback.
