Karol, we're on the same page here and I understand exactly what you are saying. My point is the same as Bill's: the fact that those of us with '95+ models cannot lock one hub at a time up front negates the driveability of having a front locker. On every moderately difficult run I have done I have witnessed others locking their fronts but leaving one hub unlocked so they can steer, then they'll lock 'em both if they have to at a hard obstacle.
What I am trying to inform you of is the fact that there are many more times while in 4wd low that you are going to want to manuever and make tight turns than there are times that you will truly need a front locker. I already have a rear locker, and can count on one hand the times that a front locker would have pulled me out of a situation that I couldn't already get out of. I have had to take a tow strap less than five times since installing my rear locker.
However I can recall hundreds of times that I was in 4wd low at extreme climbing angles while turning sharply. If my front was locked I could not have made the manuever; I would have had to go to high range and then would have been stuck without the power of low range - a true Catch-22.
Those of us with new models that install a non-selectable locker in the front will be sacrificing our ability to manuever on the trail during 95% of the run in order to be prepared for a possible advantage on the other 5% of the run at the hard obstacles, when just the rear locker might get us over that 5% anyway.
It is an individual decision for each of us, but for me I have to wait for a selectable locker. I have already found my vehicle in its current state of mods to be capable of tackling trails as tough as I care to go on. Purple Headed Monster in Oklahoma, the Airstrip and Moss Rock in Texas, Holy Cross in Colorado, and several Moab trails including Poison Spider Mesa, Porcupine Rim, Gold Bar Rim, Steelbender, etc etc. I'm having fun right now without that locker, and I prefer to be able to steer while I am on those trails.
