Got a bathmate. What cock ring should I get?

I heard you can maximize your gains from pumping by using a cock ring after you pump. I'm looking for tips on how to use it (do I just put the cock ring on RIGHT after I remove the pump or do I wait a minute?) and which cock ring would be best? Thanks for any help and all tips are welcome. Thanks
