No offence buddy,but stoping a gun dog on a runner and stoping a lurcher or calling a terrier of a kill are very far apart.I like to see a good springer or cocker working as i keep both springers and a lab myself,and it is not that difficult to stop them on a running bird same as when they flush a rabbit out of cover,but try stoping a lurcher when a rabbit or fox is pushed out,no comparison.
different dogs different jobs, ithink 3turns is abit dizzy
