Nikonos macro tube question

I moved house a couple of weeks ago and seem to have misplaced my copy of Jim Church's Nikonos book. I'm going to be using macro tubes this weekend with a 35mm lens and two strobes. Can someone with a copy of the book post the recommended apeture and focus settings please? I think the settings are the same regardless of macro tube, but it's a 1:2 tube anyway. I think it is minimum apeture, but can't remember if the focus is minimum or infinity.

Also any settings for close-up wide-angle with strobes and the 20mm lens would be appreciated.

Set the focus to minumim and close the aperture all the way. ( highest f stop) I have done it both ways, with minimum focus and infinity. It makes very little difference but the infinity focus will move the focus in back of the framer just a little bit. 2 strobes for macro?

The proper setting for the close up kit is infinity with the aperture at is highest f stop.

Thanks for the settings. I've got a pair of Ikelite 50's and only a double cord - so it's a case of neither or both. Plus two are supposed to eliminate any shadows cast by the wire framers if you use side lighting techniques, rather than a single direct overhead strobe approach, which wouldn't be casting wire frame shadows to start with.

Sorry, I was referring to using close-up techniques with a wide angle lens (20mm), rather than using the close-up kit accessory lens. The 20mm has a minimum focus length of about 14" from memory, which allows it to be used for close-up shots of objects (say a fish) that normally would appear miniscule in a traditional wide angle shot. Minimum focus is required, but I can't remember the apeture settings for using this technique with TTL strobes. I'm hoping to photograph some ling cod close up using this technique. To be honest I haven't used the 20mm at all before, so this is my first outing with it.
