I wouldn't lock your the center diff unless you get stuck. I just turned off my traction control to keep it from robbing power from me on every spin. Sometimes when trying to get out into traffic and you spin it takes all the power and you just sit there, it's dangerous.
I don't want to be the donkey's ass and poop on the fun in the snow parade. But from someone who drives on snow and ice every winter every day, well into march april, what is dangerous is driving out into traffic prematurely enough that you need enough "POWER" to merge and cut into traffic, rather than sitting there waiting for a minute longer for a better oportunity to merge. The guy behind you can wait, or eat some hitch receiver. You just need more distance between you and other cars, for everything you do on ice and snow.
VSC and systms like that are the biggest life saver after seat belts.
VSC is not dangerous. I can't think of a time where I have felt VSC took power away from me, that I felt in danger. But the first few times it comes on, it can freak you out. Beeping and blinking, and maybe trac chattering... You need to sort of practice or train for it. I know I practiced purposefully to figure it out and get comfortable with it. Now it doesn't even phase me to hear all the beeping and blinking and slowing down. It's also pretty fun. Cause when you have total control of the throtle back, you shoot out like a canon if you left your foot on the gas.
Actually, I feel like it works better if you leave you foot on the gas. Take it off, and it can't power any of the wheels to pull you in the direction of your steering wheel, but only slow you down, which might very slow down your slide into the snow bank, but not correct the slide so you avoid it.
Remember VSC is trying to prevent the slide. It doesn't know there is a car coming that is heading right for your driver side door. That is still the job of the human, to not get out infront of cars when they should have waited for a better opportunity.
That's my take on it.
Now that I'm done pooping on the party. Have fun with it while you can. I have a mount infront of my house from snow clearing, about 12Ft long, 5ft wide and 5ft tall, I can spare some. December isn't over yet, I'll get more.
