Awesome collection! I suggest a Fireman, Dutch Army Dual Pro, and/or a Master RT. I use the former and the latter quite regularly (and they're 2 out of 4 of my current 111mm). The Master RT was something I sort of pursued and finally got--by accident. I ordered a used Soldier, and the Master RT showed up instead. I didn't say a thing to the seller, although I did have to give up my beloved NIB Caterpillar ad Small Tinker, as the ordered Soldier was supposed to be a gift, and the guy I gave it to ran Caterpillar equipment for 30 years. For mechanical work, it always comes in handy. Blade can cut belts and hoses without problem, and 3 screwdrivers and a file with its aggressive metal saw and file Oh, and an Italian/Polish Police Rescue Tool. It adds a wood saw.
The Dutch Army Dual Pro and Cheese knife will probably be what completes my needs for the 111mm badge. I eat a ton of cheese, so the Cheese knife will be replacing my Opinel 12, which is just a bit too big. Dual Pro will probably be a shelf queen.
