Hole, if the blade won't break above it.
With a hole you can use and enjoy the whole (blade)
Just look at the Viele Wasp by CRKT. Premium quality materials and a useless blade. It was a great deception. I sold it. Look at the Spydie Viele. You wil see what I mean.
If you're a right hand user, but you're in an emergency situation or you're better hand is injured, you can handle the folder more easily if it's got a hole. (Eg.: with your thumb or grasp the hole between your thumb and forefinger and so on...)
The wave pattern is a very useful thing and makes the blade extremely fast - if you need it. I like it on my Emerson SOCFK1A
If you prefer stud, place it (on the blade) in the nearest possible place to the handle .
I've got a couple of good knives, but nowadays I carry the Spyderco Military, G-10 Police or Starmate the most (in this order), because they're light, strong knives and have got those practical holes

In the night I go with two blades: Military SE AND MOD Razorback SE black blade or Emerson SOCFK or Commander SE/BB. Or go with the Emerson and a Civilian. One for use, one for self defence. That's for understanding the concept. Hope it helped a little.
Anyway, your knives are good, so: stay sharp. The Doc.
