I am trying to figure out how to work with take lanes, in particular how to comp drums and other instruments that have multiple mics.  I understand how to comp on something like a vocal track where there are typically breaks so you can mute and solo various parts of a take segment by segment.  But for drums (for example) I will sometimes want to patch in a section from another take and then nudge the clips and use fades to blend them given there typically is not a clean break anywher to employ the mute tool.  This was quite easy in 8.5.3 using layers, but I can't seem to make it work in X2a using take lanes.  I can't figure out how to select the same takes from different elements (e.g., kick and snare), cut out the pieces I want and move them around. I can get to the point of selecting the correct clips, but as soon as I try to then select the appropriate time range to cut or move Sonar deselects all but one clip.  .  I am hoping I am missing something and that this is indeed possible and easy.
 
Thanks

I use track templates that allow me to mute and solo takes as folders.

What I do is use Gain Automation for the cross-fading. Keep the Gain at Unity (0db) until that lane needs to drop out. Create the Gain Automation points so that your Unity gain on a specific Lane goes to -INF (manual muting without using the Mute button) in a slanted curve, bring up another Lane that you want at the same, but inverse slant also using Gain Automation. This can be a little time-consuming, but the results can be near 100.00% accurate. I recommend not to go over unity (0db) gain, however, especially if you use a compressor on the channel, as this will affect your sound on that Track.

You should be able to do everything with take lanes that you did with layers.  The only difference is you will encounter more bugs with take lanes*.
 
One thing to definitely use on multi-mic tracks:  Clip Groups!  In Preferences, Sonar can be set to automatically group clips across tracks recorded in the same take.  Or after the fact, select multiple clips, right-click and "create selection group" (it no longer says "clip group" despite the X2 documentation).  Once grouped, selecting a clip selects all clips in its group, and you can edit as a group.
 
It would be great if we could freely edit a group without having to explicitly select a clip first.  So many times I think the group is selected, yet I'm only editing a single clip (then must undo everything and re-do as the group).  Anyways, be sure to always select a clip before trying to edit its group.
 
* Some issues with take lanes:
- Moving clips between lanes or tracks is like Plinko: you don't know where it's gonna end up until you let it go.
- Clip automation becomes unselectable.  You may have to collapse all lanes and re-expand to select a clip envelope.
- Unexpected things occur sometimes when you delete a lane.  Sometimes it deletes clips from other lanes!
- Can't recall off-hand what other take lane bugs are out there, but be careful to verify before locking in edits.
