does only betting soft lines get you limited faster

so i’ve been tiptoeing around sharper lines for a while, just because i hate getting limited or forced onto lower stake stuff, but it’s hard to resist when the soft lines just pop up right there. the thing is, i keep hearing from a couple people that if you only touch those soft lines, especially live or early openers, the books will tag you way faster than if you blend in a bunch of action on sharper stuff or even the fun longshots.

i don’t really care much about parlays or random action, but do you actually get flagged way quicker if your betting is like all soft openers and nothing else? or does the mix really matter that much in the end? anyone ever try disguising their action and did it actually help with limits?
