Just have both, stops the arguments and the headache. A Whippet SHOULD be able to do the same as a lurcher of similar size, but obviously not going to be comparable to a bigger dog at many things. People also look down at them, but they are a very handy thing in the mix of a good lurcher, so if no one was working pure greys or whips then there would only be shite out there to use. I know many lurchers and lurcherxlurcher and thats the way to go sure, but at the start of these lines, some one needs a whip/grey thats doing the buisness to a high standard - i.e bull/whip, beddy/whip, grey/whip,
