The best reaon I can give for raising the flop is the fact that there just isn't the same level of respect for flop raises as there is for turn raises. You can raise someone on the flop and still get people to call 2 with middle pair, people will 3-bet you with top pair, and do all sorts of other good things when you have a set.

When you wait til the turn, many players will now fold to a raise when they would have called a flop raise as well as a turn/river bet.

Plus a lot of my sets go more like this anyway. Guy bets, I raise, he 3-bets, I call. Turn: he bets, I raise.

There are times when waiting til the turn is correct, but I really suggest you try playing them fast for a while and see how it works out for you.
