Get used to it. Simple. If you can squat the weight, who cares how it feels coming out? I think some people just find the unrack and walkout hard. It could be symptomatic of a weak point too - maybe you aren't tight enough unracking? I've noticed when I go heavy if I get super tight to unrack and walk out it can feel like the bar is pretty light and that's a massive help mentally.
I found that squats against bands helped clean my unbanded walkout up a lot - simply because I had to get way tighter unracking so as not to get pulled all over the place by the bands. Or you could try really heavy walkouts, something like 120% of your max with the pins set super high or a spotter just in case.
Don't get too hung up on not having a mono. I love them, but where I train doesn't have one and in a way I'm glad because it forces me to get better at walking out my squats. A mono in competition is then a breath of fresh air for me - that being said, I set up in a rack as if I'm in a mono and THEN walk out: I set my feet to unrack exactly as I do to squat, and then walk out from there. It could be that may also help you if you're not doing it already.
