Does anyone here use a springpole for your yorkie to ''hang on'' ?

Sorry my english isnt good.
I'm thinking of making a springpole for Fido !
Yorkies are true Terriers, I like working with the Terrier instinct, the yorkie is made for catching a pray (rat,mouse etc.) hold it and not let go, and kill it.
If Fido has a squeeky toy he bites it until he can't squeek no more

And about 2 weeks ago I was walking with him off-leash and I lost him after a bird! couldnt catch him haha, but the bird stood on the same place so I ran after Fido and cought him finally.
How do your yorkies like the springpole ? how long can they hang on it?
