Haha, not so sure about the 'best', but most sites have the episodes divided into parts. Here is one with your requested ' full length', though! I made sure they have your requested 206 subbed (: http://www.animeseason.com/bleach Just scroll to Episode 206!
(: I checked and the first video player they give you is Flash, and it might have 'exceeded the playing limit' for a day. If that's the case, just click on the next tab that says 'Other Players' and it'll give you the Youtube version of the full episode divided into three videos, nevertheless the full episode (: Hope this helps! You could always just check out different anime viewing sites for future reference!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
