As in all things, get out and record both ways. See which you like the 
best under each kind of situation. There are no hard and fast rules.

Remember, that switch is in there for a "distant" recording that would 
be our "close" recording. It won't near handle compensating for our 
medium or distant recordings.

And, if using the mic with a parabolic, it might make it tougher if you 
wanted to fully remove the 'parabolic effect'. As you may have gathered 
I'm not one to find much need to remove that.

I almost always use my MKH mics set straight, no compensation set. I can 
deal with that in the computer. I do sometimes use the Telinga with it's 
low cut set, but will have tried it both ways before doing that.
