transition layer cruising
In Spain the transition altitude is 6000 ft except in a few places as the canary, and hence the Transition level usually is FL70.
The altimeter setting is QNH when cruising at or below the TA. The standard setting (1003) is used when cruising at or above TL.
We also know how to set the kollsman when climbing or descending.
Hence, I can assume that cruising at the Transition Layer is not allowed. However, I have cruise a lot of times at 6500 ft, this altiude is a good cruising altitude for a VFR piston engine given a good range, speed, and a good visual range...
Should I carry on cruising within the TL or the TL only applies at the Aerodromes vicinities ?

Standard pressure setting down under is 1013, guess that must be because there is more atmosphere above us 
But at least there's a sensible transition layer of A100-F110. VFR aircraft rarely need F105.
I'd say that it is unsafe to cruise in the transition layer where there may be a significant difference between standard and local QNH, terminal area or not.
