Don't use the first screen-shot as a reference for the 06's quality over any other transfers, as that was clearly sourced from some original film stock. But check out other shots and see how you feel. I think you'll see what Moth3r means about the quality kinda varying in different aspects. But overall I'd say go with 06. Unless you want to get each and every transfer there to reap the benefits each different one can offer shot to shot.
If you computer crashes this week you're fucked. Just stop encoding now and save some time. If you want to go check out the avisynth frameserver program, that'd be a great way to make a very small file that just sources the video from your HD source. I'm pretty sure Womble takes avisynth files too. In fact I can think of the script now.
