Looks like I'm going to have to dig through my hand histories a bit then
Even the cookie-cutter advice was quite helpful; The rest is going to take me a while to chew on and digest, but I'm sure I'll integrate it into my play eventually.
(I like to try and make one change to my game at a time, or as few as possible so I can tweak and fix without introducing more leaks)

It might do well for me to explain that I play poker through a virtual machine (I run linux as my operating system).
I lost most of my hand histories a while ago when I deleted the virtual hard-disk without thinking :-S
Now I mostly just have omaha 6-max cash game hand-histories backed up, but I'm sure I kept an alternative backup of the hold'em hands I've played in the past; Time to get looking.
