My thoughts are exactly the same....
Trailer Park: This map is pretty good on S&

, but any other mode it's fairly terrible. Tubes constantly being fired through trailer windows so leads me to go round outsides of the map. But to no avail does this seem to work for me. Example: enemies spawning right behind me, again Tubes then when killstreaks come into air i rarely have anywhere to get cover. This map just wants to rape me all the time, except for the odd time it gets friction burn.
Carnival: Right, at first i hated it, now? I still hate it, everytime im one kill away from a major killstreak... BOOM! Camper strikes again! Theres jus so many places to camp i find it nearly impossible to do really well on this map. I might aswell camp myself and fuukin OMA tube everybody i see, because its hard to consistently get kills moving from spot to to spot. At least, i find.
Fuel: Love it! Apart from the rock glitch this map is amazing. I can move around this map quite easily and rack up the kills, and cover is never to far away unless your around the 'rock'. And many different firing lines which has its dis and ad'vantages. Mainly for me, its an ad. This map puts soothing cream around my a'hole after trailers done with me.
Cod4 maps im not gonna go through, ive played them enough im good at them both.
