what ver of (k)ubuntu is most suitable for tde

Greetings Believe it or not I've only come across a reference to trinity in the last week or so when checking out porteus usb-stick linux. It really cheered me up that kde3 (as tde) is still not only alive but seemingly very healthy! At present I am still using kubuntu 8.04 for obvious reasons but would be delighted to install a more up-to-date os and tde on another partition on my hard drive. I have already downloaded kubuntu 12.04 (always in the hope, in vain, that it had somehow become more kde3 than kde4!) but I don't see any mention of (k)ubuntu 12.04 in the installation instruction page, so I presume I should use a release from last year. Also I notice that ubuntu 11.10 is mentioned rather than kubuntu 11.10. Is it recommended that I use ubuntu 11.10 rather than kubuntu 11.10 in case of conflicts? Or does it matter at all? I also have an iso of xubuntu 11.10 - would that be suitable? Any advice would be welcomed. Thanks Lou
