Polish Messengers/Communicators

I wonder which of Polish messengers would work properly on older PC? I am interested in Polish messengers(communicators) using Gadu-Gadu protocol... Thanks a lot for your answer. :-D

konnekt from: konnekt.info/download.html
aqq from: aqq.eu

I recommend aqq it is working light and smooth

I will try AQQ. I downloaded unofficial portable Konnekt but it's size was about 50MB! :-O Well, it's really bad there is no Polish IM klient without adds. I tried Pidgin but Gadu Gadu doesn't work there, I still don't know why. Miranda could be ok but I don't have time and knowledge to configure it... Anyway, thanks for your answer. :-D

Tlen uses besides its own also a gg protocol and gg network. Has got a better encryption message plus locally stored passwords.

I heard about Tlen it should be the second most popular messenger in Poland right after Gadu-Gadu. And Tlen is also a Jabber client like AQQ. It seems guys in Poland love Jabber. :-D But don't forget I want a messenger for an old(slow) PC and I read somewhere Tlen can slow down PC... Now I'm testing Spick... And I have found another messenger without adds that you can find at site k2t.eu/wtw/.
