congrats on sergeant man! i saw your posts on regular gatherings. until that gets set in stone , we could make a regular gathering if u want. i definately could use the practice and im sure others would be available.
i have read about heatmaps on the cod site. cant register my profile on the wii and computer is down. also found an independent heatmap generator that you can use aggrigate stats from anywhere. 30 day free trail, after that i might be able to finance or help finance if it turned out to be a good tool. hit me back. site is logixML.com
as far as a heat map goes, i found heat maps for halo3 on bungie.net, so i guess that it would be a possibility that treyarch could have made something similar, i just havent found it yet.
