well, we play epl in centurio and d2 in millennium (since this is first open division) and if you compare these two epl is stronger for sure. it's like somewhere between d1 and spl (plus tonton and icon, hpg with bshort is strong too) but there are also some weak teams that shouldnt really play this division.
in istambul there was perfect turf and weather just like in malaga. huuuuge drawback were filling station (one filling port for two xball teams that filled only up to ~3k! one word - insane). and turkish kids walking around you all the time looking for something to steal.
last year centurios were just fine, of course millennium is better organized and stuff but centurio is not bad. just some silly complaints from time to time, other than that it's good. oh and this year's locations are way too far...
btw. in istambul there was a d2(not xball) team made of 2 turkish guys + davey williamson + patrick wrobel (f.syndicate) + victor zemen (bullets)
