I'm not sure about Griffons, but with FKS I have to use trekkers with the low climbing bar up, I assume this is the same for Griffons. It's not a big deal at all for me, because I don't do any long flats or traverses while touring but if you're going farther than a 1000 ft on flats then it might get annoying, or you could get used to it.
I think most people who break trekkers have them adjusted too tight for their boot and put too much unneeded stress on weak parts or fall with them on. They don't have to be super tight, just tight enough so your boot doesn't fall out. I find that the downfalls of trekkers are:
-the size - they actually take up a deceiving amount of room because of their shape which means you can't really take super small packs for sidecountry laps or whatever when you already need to fit skins, shovel, probe, extra layer, lunch etc...
-they are high off the ski and theres quite a bit of lateral play - this is fine if you're skis are laterally level like on a cat track, straight up a run, or on a traverse or side hill that was made in softer snow. but it sucks on a steep, firm slope (i assume you wont be seeing this in the backcountry).
Personally, I use trekkers because I'm scared shitless of using touring bindings on my everyday charging ski that I rail super hard in crud and big mountain comps, and I can't really afford to put another set of skis and expensive bindings in my quiver when I dont tour very much. Eventually I plan on putting a pair of dukes on a pair of skis, but trekkers work well enough for me for the time being.
I think you will be fine with trekkers if you're not doing long trips/expeditions, don't mind a little extra weight, and only tour a couple times a year.
