don't bother with trekkers. If you're doing less than 5 tours in a year, they make sense, untill you try and actually go anywhere with them. More worthwhile finding someone who has touring skins you can borrrow IMO.
As far as the Fritchsi goes, it's a lot more solid than most people give it credit for. Just spent 15 days shredding icy chunky variable snow on an older pair, and only released once. \And the newer ones are even beefier.
Dynafit BINDINGS are awesome. nothing compares to them. but watch out, and make sure you can find a boot that will work for you before you go with that system, because ther's very few perfoming beets out there that are compatible.
I'd say the best bet for most people on here looking for a "touring" binding would be the in-betweeners like marker salomon, tyrolia, etc. because you still feel like your foot is in a regular binding that you can trust, but with the ability to free your heel every now and then.
