I've never ridden Targas, but I hear they're stiffer than the 390s, also the big difference to consider is the cant bed system. If thats not appealing then go with the 390s, if it is but you still want a softer binding, then take a look at the 390 bosses. I ride bosses and they're pretty awesome. The cant bed really helps with the knees and then if you're riding a rocker it really helps with tip to tail power. The flex is fairly soft, but I can still ride the whole mountain.
