the vast majority of the deathmatch servers i think are TDMs in fact
well it has its upsides too like its less energy consuming the fact that your face less targets given any period of time and sometimes i find it easier to focus on an audiobook for instance while i play TDM rather than FFA DM
yeh like NAVI DMs or SKILLZ.LV DM only that i doubt they will work for you as good as they work for me for instance (i have less than twenty ms of latency on each one of these) because of the you know so called internet topography

and as for pings go its not the distance that matters most its the peering so i thinking you should install HLSW (looks like this http://img716.imageshack.us/img716/3170/001ac.png thats actually mai CSDM pubs collection =D) and figure out your own patterns yourself (you know like try to determine which hosts in a foreign country work better for you than the other ones they are not all the same =D)
also there are also these two polish FFA DMs you can try

188.8.131.52:27015 LukMAN DM [ESL maps] [1000fps]
from mai general experience the first one (1shot...) should probably give better pings to foreign peers
its pretty obvious. You would get used to kill everyone in the server, do that in cw and tell me how it goes. Also in standard dm you practice hearing steps and reacting to a teammate or an enemy faster.
i'm playing only ffa and i find it better than normal dm because on ffa your reflex is getting better and you have to stay more focus on the game than on normal dm.
and you should be a little bit...idk...noob maybe to kill your own teammates in a cw match after you played ffa dm. i never faced with this problem.
