One method is to:

Lay your vision tracks normally, on say V1-V4, and sync them up. Make V1 your 'master' or primary source, if you have one.
Add a track above and fill it with slug from the viewer pulldown menu.
Select the vision tracks and opt-then shift-drag to duplicate them on an equivalent set of tracks above the slug.
If all or any of the tracks contain multiple clips, select each track in turn and nest it.
Resize each duplicate track (using the Image & Wireframe mode, 'W') to achieve a picture-in-picture effect, perhaps side-by-side, or offset. With four tracks, each neatly occupies a quarter of the frame.The slug track becomes a black (or coloured, if you prefer) background over which they all sit.
Then select "Play Base Layer Only' from your pulldown RT button near the Sequence tab. What happens? The composite disappears, revealing just V1, but nothing will need rendering to play. Stop, and your composite returns.
Go through and use the razorblade tool (b) on V2, V3, or whatever every time the master shot turns to custard, and play through til you want to return to the master. Slice the track and shift-drag it down to V1. If you want to see the new vision play down to an outpoint before cutting it, solo it using ^s. Otherwise, when you play what you'll see is V1, but when you stop, or nudge through frame-by-frame around a cut, you'll see a composite of both tracks, on V3 & V4, a kind of 'live trim window' that vanishes when you play.
Using this method fine trimming is easy - shuffle your way to the sync cutpoint you'd really like, watching both sources in the same monitor, select the edit point and hit 'e' to snap it to the playhead.
If you hit opt-p you'll advance down the timeline as quickly as your machine can render the composite, to help you pick a cut point. On a fast G4, that'll be close to real time.
Now, when you take a break by all means render the composite so you can see all sources at once, but that'll mean you'll lose full frame playing of your 'Base layer'. But you can get it back easily, and selectively, by using the multi-track blade (b-b). As you chop up the sequence and drag your vision down, your rendered composite vanishes, between the cuts. Trim it back a bit and you can still see the cuts full frame, but with the rest of the rendered composite intact...a rare case where 'unrendering' a track is actually helpful.
