Identifying a big leak in my game (no hand content)

[vulturesrow]

As I close in on my first 10000 hands, I started checking the stats. The most concern I have is in two areas. One is agression. My flop aggression (~1.91) is less than my turn aggression (~2.01) which is less than my river aggression (~2.11), basiscally 180 out from how it should be and my with the numbers being too low I think. This ties right in with my other major stat discrepancy, my W$SD, which is right at about 43%. I filtered my stats to see which hands lost the most money for me when I went to showdown. It confirmed what I had suspected, that I have been pushing big pairs too hard. In fact most of the hands that I have lost the most with when I went to showdown are some of my overall best winners. Right now my BB/100 is 4.1 so I cant complain there, but obviously I have some major leaks.

My point in discussing this is twofold. One is I wanted to show an example of using PT to identify leaks, and two, I would like some inputs from other posters on what you think these numbers mean to you as an objective observer, and any advice you might have. Thanks in advance.
