Oceanic Probe dump valve question

I have an Oceanic Probe QLR BC. I have been using it for the past 10 dives. I only have one problem with it.
I am having trouble finding the handles to activate my dump valves. They are small round balls, one on my shoulder, the other is by the quick-release for my weights. The handles are so small that I have trouble feeling around for them. Of course I cant see them either so I am going by feel only.

Any ideas?

Practice, practice, practice in a pool or confined water until you can find them without thinking.

Then Practice, practice, practice in a pool or confined water in different positions (like upside down, horizontal, etc.)

Then Practice, practice, practice in a pool or confined water in a blacked out mask (tin foil over the front works too)

If that doesn't work, then talk to your dive shop about ideas they may have about bigger handles/knobs to make it easier to find. I would stay away from modifying your equipment.

Practice, practice, practice,that's the only way to do it.
As a new diver or diver new to the gear,you have to practice to find all pieces of you gear blind.
So go to a pool and practice.
