i own a half cross beddy whip that i bred my self. i couldn't be more please with her at the moment, a perfect ferreting dog which is what i want her for mostly, and shes coming on well on the lamp. I'd say she can turn tighter than my mates dog(21 inc beddy whip x Colly Grey. ). and she isn't much slower either. but i have never seen a 3/4 bred cross work so i can't say which is best , but mine ticks all the box's for the work i do.
