My standard is Kadee #58's. I also neuter them of their glad hands since I do not use magnetic uncoupling. An added benefit of neutering is the effort to uncouple with a skewer is even easier since the knuckles are free of the resistance of moving the gladhands along for the ride as well.
I proved this while operating at a friends house and finding it slightly more difficult to uncouple. I realized it had to be the glad hands on his equipment requiring more effort while twisting the skewer.
By the way, instead of barbeque skewers, I actually use an 8 inch length of 3/16" diameter wood dowel with one end sharpened in a pencil sharpener and deburred with some sandpaper.
