I like Twista but i can agree he's best in short bursts like Big Pun, unlike alot of white guys who rap really fast cause they think that's the height of technical skill, Twista's brings a sense of melody and control to his rapping and he can actually slow his flow down if the track calls for it
his rapping style makes sense when you know that he was rapping over house before he went to rap not only that but he said in an old Combat Jack interview that he was really into rhythmic patterns so when he was coming up with raps he'd recite them slow at first and do em faster and faster through practise.
