I hope I've understood where you guys are at, but here's my input:
If you are using take lanes, the Smart tool will change the cursor to what looks like a honey scoop when moved to the bottom half of a clip.
Clicking here will select the clip and mute all the others in that stack of clips.
The clip will also appear in the main track at the top.
Once you have the selection of clips you like, you have some choices.
1. Flatten the comp (right click and select Flatten comp) or...
2. Close the take lanes and copy (Ctrl+drag 'n' drop) the track into a fresh, empty track.
