That was my line of thinking too. But then I also thought about a Pioneer or PX for the inline awl, or a PTC... See where I am going with this? So the solution was to ask the people that are just as nuts about MT‘s (and that like to go through mental exercises and what-if scenarios) than I am.
Well if you want to know what I decided on when I got my pants back on, it's the Pioneer X. Back to square one. It's not the lightest system there ever was. Also, the openers would be redundant. The reason I stayed with the Pioneer X is because once I shed my bag and keys, the Pioneer X is a great stand alone tool.
The one I always carry with pretty much every Gerber I own (except my MP400, which already has scissors) is the Huntsman, since none of my other Gerbers have scissors or a saw.
It is a great tool, but for some reason I have never taken a liking to it
The Swisstool Spirit will cover you well. And if you put the MP600 on your belt on one side and the Spirit on the other side, you will be perfectly balanced, physically at least 😜. But the Compact would probably be better. 👍.
...I would second the Compact in your case... Or the Waiter if you don't need scissors. (But everyone needs scissors)...
