Oh, in the spirit of reporting back, if anybody's still interested.
Still getting a bit more shaping than expected on torrents after hours on weekdays, although it's generally fast, and definitely better than I was getting on Mweb.
Also, as per the article on MyBB the other day, the SEACOM cable break hasn't actually been fixed, so we (SA) probably aren't back to full international capacity yet anyway. So we'll see what happens on that front come May.
However - my streaming speeds (esp from Youtube) are FAST. I can now stream 480p from Youtube without manually buffering first (pause the vid) - ON A 1 MEG LINE!!
VERY nice. So I ended up spending more for my bandwidth account, but now I won't be thinking about upgrading my line speed everytime I stream a video. So I'm kinda actually saving.
