totally agree its a well kmown fact ,lines can be improved through in and linebreeding but thats seriuos hard work with no guarantee of succcess ,,when it comes to selling to the public crosses give instant vigour and also hide rececives under the carpet unfortuantley after several generations of safe crosses your stock had aquired rececives from each of those crosses when that line is later inbred and everything under the carpet gets revealed inbreeding gets the blame when all it did was reveal what was already there,, ,imo there only one way to find out if pure haze can be improved by inbreeding and that of course is inbreeding it and seeing for selfDespite what Sam and Nevil have said, I'm not convinced that haze can't be improved through selection and inbreeding. Case in point: Tom Hill Haze.
