I wouldn't stab the terminals at all i mean after a while yur gonna have problems...when troubleshooting circuits in a dwelling half the time it all goes back to those stab terminals. because when u push the device back in the box it sometimes loosens up the stab and makes a loose connecton that may cause arcing..then when trying to find the problem you pull the device back out...and the stab terminal tightens making a good connection thinking you don't have a problem... so i would not suggest the stab in terminals.
