Call Of Duty WAW Classes

I just began playing Call Of Duty World At War and was wondering what the best perks with guns are... I like the Thompson and PPSH with stopping power and Bouncing Betty's... (rest depends) I would really appreciate it if you could tell me some of the best combo of perks and guns you use.

Thanks for your input, I will try it out... lol your the only one to write back so far and its been up for 2 days
