DJ V does sound more catchy! DJ IV (as in Ivy) might be another option, especially if the number 4 has any major significance in your life (IV is the roman number for 4) I don't have any equipment to DJ at venues yet, but is getting my hands dirty experimenting and producing tunes in Fruity Loops. At the moment I'm just playing and not doing anything serious with it, but when time permits, I'll commit to producing some serious tunes!
