Preflop Betting Debate

I have read both HOH1 & HOH2 & I just started Phil Gordan's Little Green Book. Harrington advises to make larger raises from early position to eliminate more players, and based on the fact that you don't mind taking the pot down right there out of position. He especially emphasizes this with 99-JJ as these are hands that don't want a lot of action. Phil Gordan raises less from early position and more from later position. He says that he would rather get more money in the pot when he is at a positional advantage and less money in the pot when he is out of position. I understand the logic but by making larger raises from late position, you are less likely to be able to take advantage of being in position because you are less likely to get callers. On the other hand, when you make smaller raises from early position you are only making your positional disadvantage worse by inviting more people into the pot. You may end up against several players out of position which is exactly what you don't want. Is my thinking right here? I was just wondering what others' opinions on this were. I was wondering if anyone has tried both of these strategies and seen more success with one or the other. I am leaning toward staying with Harrington's strategy and not even giving Phil's a shot. Harrington's seems to work pretty good and let's be honest here: he's had a lot more success than Phil Gordan.
