Francesco,

I 'got into' trying DBI about 35 years ago using Pinakryptol Green  
pre-development bath
with occasional 'second half of development time' of observation with  
green safelight
during tray development....  a practice recommended by a friend

I (personally) was not convinced that it was worth the trouble.. the  
$ cost... and gave it up
up after finding that 'my film speed' of the film was reduced by just  
over half.

But...  since then, I have on a few but rare occasions used short  
green-safelight inspection
of film observing the back of the film (without any Pinakryptol pre- 
development soaking)
but again... only after at least half development time has passed.

By the same token... I have not tried Pinakryptol yellow.
