I tried loosening a track nut on my bike so I could flip the wheel over for a long hill climb (I had forgotten my 15mm wrench at home, that's another story) and I wrecked one of my track nuts completely when I tried to use an adjustable wrench I had on me.
I feel that a closed ended 15mm wrench will work perfectly, and that there is no substitute for it.
Mine is a high quality model. Also, with the chain tensioners in place I don't need to crank down on the track nuts quite so hard to keep the wheel from slipping. I do plan on getting a dedicated wrench eventually though.
