A challenge for a 5-limit semisixths comma pump comparison

Hi again.
Not very long ago, a couple of us were discussing various attitudes to 5-limit comma pumps. Soon after that, Gene posted a link to his examples as well. And because so far only the two of us seem to have presented some clearly 5-limit ones (with Mike's hanson pump being one exception), I think this might be an interesting question for others as well:
If you wanted to make a chord progression where the first and last chords differ by 78732/78125, what would that be like?
I think it may be interesting to compare the answers and therefore get more aware about other people's preferred methods.
So if you feel like finding one, feel free to do so.

I have a few of them, actually. Here's what I have so far

Blackwood - http://soundcloud.com/mikebattagliamusic/blackwood-comma-pump
Hanson - http://soundcloud.com/mikebattagliamusic/hanson-comma-pump
Porcupine - http://soundcloud.com/mikebattagliamusic/functionalporcupineexcerpt

Also one 7-limit one -

I'd be down to take this challenge, but it's going to have to wait a
bit - just moved into a new apartment today, the sky is falling down
at work, and this linear algebra library needs to get moving!
