Due to the fact i play a lot of COH 2 and test a lot of maps i can highly recommend to use these maps in an upcoming BK Map Pack. All maps are very tactical, without errors and professional made:

Downtown by TheSphinx (and is working on Drachenwald)
Eberswalde by Stahlhagel
Wolfsschanze normal + rain by Stahlhagel
Operation Herbstnebel by O´Field
Krasnoye Selo Rasputitsa Time + normal by Nebaka
Sainte Mere Eglise by Kibe777
Pinsk Marshes Winter Battle by O`Field

To Popcap my opinion is a) best tactical gameplay is with 100,120 or 125 PoP and b) with higher Pop´s are more ai units on the field the client have to work with so the performance/fps is going down rapidly.
