I understand your reasons for avoiding it.
You *should* be able to get tight and feel comfortable using a belt with any weight and any lift, so it's possible that you need to tweak the way you brace into it.
Right now my belt is annoying loose, with squat I'm struggling to feel it at the top of the rep at all. The next notch in will be slightly too tight though, so I'll just have to live with it until I get fatter/thinner.
