New Collar Research

Being a sub a collar is very important to me, I love how it makes me feel when a Mistress puts it on me.
At the weekend I cleaned my collar, it's a series of rectangular metal links held together by a leather collar threaded through it.
However, I think it's time for an upgrade and want it to incorporate some features that might work well with some favorite activities.
I love being choked with a dog lead during play, so I decided to look at some of the options and possibly something custom.
I've looked at the Martingale style and also the Quick-Pull Choke Collar
I'm worried the Martingale wont give her the satisfying squeeze around my throat the dog lead gives her, the quick-pull might but I need something that can be shown off,

Any suggestions?
