I don't understand all the pre-occupation with night and instrument time.
There are 100s of VFR only commercial helicopter pilots in Canada and they seem to do quite well. The majority of the VFR fleet does not have the basic instruments to keep the aircraft upright in IMC nor are they required by regulation.
The VFR helicopter pilot only needs enough instrument time to realize that he will perish if attempting IMC flight if not properly trained or in an aircraft with out the required instruments.
Like I said early there are very professional VFR only helicopter pilots out there with no interest in ever flying at night or IMC.
