It would suck to do Fish East with no winch. There are times when we have had 4 different jeeps winching to 4 different spots. With no lockers and no winch it might be a disaster.
Of course, if the trail is mainly frozen bottoms than you might be ok.
The only caveat is that if one rig shows up with no winch, than others will too.
The other thing Dom is that some holes are off camber as well so a lot of flexing occurs.
Either way, you guys will have a long day, winch or no winch.
If i remember correctly, the CJA had a 33+ tire rule and a winch for this run, than the locked and loaded rubi came out on 31's and they were allowed too.
