im probebly one of the ones who say get a beddy x whippet without seeing many of them worked in the first place, so can see where your coming from ,though i had a beddy x grey about 15 years ago that was a good lamper ,great ferreter ,crap on hares day and night ,jumped like a stag and was great around dogs and people
and the reason i say beddyx whippet is if my old dog ted was ok then im sure a well bred beddyxwhippet should in theory be just as good.this is only my opinion mind ..
